# Porting to the Buffer.from/Buffer.alloc API
|
||||
|
||||
<a id="overview"></a>
|
||||
## Overview
|
||||
|
||||
- [Variant 1: Drop support for Node.js ≤ 4.4.x and 5.0.0 — 5.9.x.](#variant-1) (*recommended*)
|
||||
- [Variant 2: Use a polyfill](#variant-2)
|
||||
- [Variant 3: manual detection, with safeguards](#variant-3)
|
||||
|
||||
### Finding problematic bits of code using grep
|
||||
|
||||
Just run `grep -nrE '[^a-zA-Z](Slow)?Buffer\s*\(' --exclude-dir node_modules`.
|
||||
|
||||
It will find all the potentially unsafe places in your own code (with some considerably unlikely
|
||||
exceptions).
|
||||
|
||||
### Finding problematic bits of code using Node.js 8
|
||||
|
||||
If you’re using Node.js ≥ 8.0.0 (which is recommended), Node.js exposes multiple options that help with finding the relevant pieces of code:
|
||||
|
||||
- `--trace-warnings` will make Node.js show a stack trace for this warning and other warnings that are printed by Node.js.
|
||||
- `--trace-deprecation` does the same thing, but only for deprecation warnings.
|
||||
- `--pending-deprecation` will show more types of deprecation warnings. In particular, it will show the `Buffer()` deprecation warning, even on Node.js 8.
|
||||
|
||||
You can set these flags using an environment variable:
|
||||
|
||||
```console
|
||||
$ export NODE_OPTIONS='--trace-warnings --pending-deprecation'
|
||||
$ cat example.js
|
||||
'use strict';
|
||||
const foo = new Buffer('foo');
|
||||
$ node example.js
|
||||
(node:7147) [DEP0005] DeprecationWarning: The Buffer() and new Buffer() constructors are not recommended for use due to security and usability concerns. Please use the new Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() construction methods instead.
|
||||
at showFlaggedDeprecation (buffer.js:127:13)
|
||||
at new Buffer (buffer.js:148:3)
|
||||
at Object.<anonymous> (/path/to/example.js:2:13)
|
||||
[... more stack trace lines ...]
|
||||
```
|
||||
|
||||
### Finding problematic bits of code using linters
|
||||
|
||||
Eslint rules [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor)
|
||||
or
|
||||
[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md)
|
||||
also find calls to deprecated `Buffer()` API. Those rules are included in some pre-sets.
|
||||
|
||||
There is a drawback, though, that it doesn't always
|
||||
[work correctly](https://github.com/chalker/safer-buffer#why-not-safe-buffer) when `Buffer` is
|
||||
overriden e.g. with a polyfill, so recommended is a combination of this and some other method
|
||||
described above.
|
||||
|
||||
<a id="variant-1"></a>
|
||||
## Variant 1: Drop support for Node.js ≤ 4.4.x and 5.0.0 — 5.9.x.
|
||||
|
||||
This is the recommended solution nowadays that would imply only minimal overhead.
|
||||
|
||||
The Node.js 5.x release line has been unsupported since July 2016, and the Node.js 4.x release line reaches its End of Life in April 2018 (→ [Schedule](https://github.com/nodejs/Release#release-schedule)). This means that these versions of Node.js will *not* receive any updates, even in case of security issues, so using these release lines should be avoided, if at all possible.
|
||||
|
||||
What you would do in this case is to convert all `new Buffer()` or `Buffer()` calls to use `Buffer.alloc()` or `Buffer.from()`, in the following way:
|
||||
|
||||
- For `new Buffer(number)`, replace it with `Buffer.alloc(number)`.
|
||||
- For `new Buffer(string)` (or `new Buffer(string, encoding)`), replace it with `Buffer.from(string)` (or `Buffer.from(string, encoding)`).
|
||||
- For all other combinations of arguments (these are much rarer), also replace `new Buffer(...arguments)` with `Buffer.from(...arguments)`.
|
||||
|
||||
Note that `Buffer.alloc()` is also _faster_ on the current Node.js versions than
|
||||
`new Buffer(size).fill(0)`, which is what you would otherwise need to ensure zero-filling.
|
||||
|
||||
Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor)
|
||||
or
|
||||
[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md)
|
||||
is recommended to avoid accidential unsafe Buffer API usage.
|
||||
|
||||
There is also a [JSCodeshift codemod](https://github.com/joyeecheung/node-dep-codemod#dep005)
|
||||
for automatically migrating Buffer constructors to `Buffer.alloc()` or `Buffer.from()`.
|
||||
Note that it currently only works with cases where the arguments are literals or where the
|
||||
constructor is invoked with two arguments.
|
||||
|
||||
_If you currently support those older Node.js versions and dropping them would be a semver-major change
|
||||
for you, or if you support older branches of your packages, consider using [Variant 2](#variant-2)
|
||||
or [Variant 3](#variant-3) on older branches, so people using those older branches will also receive
|
||||
the fix. That way, you will eradicate potential issues caused by unguarded Buffer API usage and
|
||||
your users will not observe a runtime deprecation warning when running your code on Node.js 10._
|
||||
|
||||
<a id="variant-2"></a>
|
||||
## Variant 2: Use a polyfill
|
||||
|
||||
Utilize [safer-buffer](https://www.npmjs.com/package/safer-buffer) as a polyfill to support older
|
||||
Node.js versions.
|
||||
|
||||
You would take exacly the same steps as in [Variant 1](#variant-1), but with a polyfill
|
||||
`const Buffer = require('safer-buffer').Buffer` in all files where you use the new `Buffer` api.
|
||||
|
||||
Make sure that you do not use old `new Buffer` API — in any files where the line above is added,
|
||||
using old `new Buffer()` API will _throw_. It will be easy to notice that in CI, though.
|
||||
|
||||
Alternatively, you could use [buffer-from](https://www.npmjs.com/package/buffer-from) and/or
|
||||
[buffer-alloc](https://www.npmjs.com/package/buffer-alloc) [ponyfills](https://ponyfill.com/) —
|
||||
those are great, the only downsides being 4 deps in the tree and slightly more code changes to
|
||||
migrate off them (as you would be using e.g. `Buffer.from` under a different name). If you need only
|
||||
`Buffer.from` polyfilled — `buffer-from` alone which comes with no extra dependencies.
|
||||
|
||||
_Alternatively, you could use [safe-buffer](https://www.npmjs.com/package/safe-buffer) — it also
|
||||
provides a polyfill, but takes a different approach which has
|
||||
[it's drawbacks](https://github.com/chalker/safer-buffer#why-not-safe-buffer). It will allow you
|
||||
to also use the older `new Buffer()` API in your code, though — but that's arguably a benefit, as
|
||||
it is problematic, can cause issues in your code, and will start emitting runtime deprecation
|
||||
warnings starting with Node.js 10._
|
||||
|
||||
Note that in either case, it is important that you also remove all calls to the old Buffer
|
||||
API manually — just throwing in `safe-buffer` doesn't fix the problem by itself, it just provides
|
||||
a polyfill for the new API. I have seen people doing that mistake.
|
||||
|
||||
Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor)
|
||||
or
|
||||
[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md)
|
||||
is recommended.
|
||||
|
||||
_Don't forget to drop the polyfill usage once you drop support for Node.js < 4.5.0._
|
||||
|
||||
<a id="variant-3"></a>
|
||||
## Variant 3 — manual detection, with safeguards
|
||||
|
||||
This is useful if you create Buffer instances in only a few places (e.g. one), or you have your own
|
||||
wrapper around them.
|
||||
|
||||
### Buffer(0)
|
||||
|
||||
This special case for creating empty buffers can be safely replaced with `Buffer.concat([])`, which
|
||||
returns the same result all the way down to Node.js 0.8.x.
|
||||
|
||||
### Buffer(notNumber)
|
||||
|
||||
Before:
|
||||
|
||||
```js
|
||||
var buf = new Buffer(notNumber, encoding);
|
||||
```
|
||||
|
||||
After:
|
||||
|
||||
```js
|
||||
var buf;
|
||||
if (Buffer.from && Buffer.from !== Uint8Array.from) {
|
||||
buf = Buffer.from(notNumber, encoding);
|
||||
} else {
|
||||
if (typeof notNumber === 'number')
|
||||
throw new Error('The "size" argument must be of type number.');
|
||||
buf = new Buffer(notNumber, encoding);
|
||||
}
|
||||
```
|
||||
|
||||
`encoding` is optional.
|
||||
|
||||
Note that the `typeof notNumber` before `new Buffer` is required (for cases when `notNumber` argument is not
|
||||
hard-coded) and _is not caused by the deprecation of Buffer constructor_ — it's exactly _why_ the
|
||||
Buffer constructor is deprecated. Ecosystem packages lacking this type-check caused numereous
|
||||
security issues — situations when unsanitized user input could end up in the `Buffer(arg)` create
|
||||
problems ranging from DoS to leaking sensitive information to the attacker from the process memory.
|
||||
|
||||
When `notNumber` argument is hardcoded (e.g. literal `"abc"` or `[0,1,2]`), the `typeof` check can
|
||||
be omitted.
|
||||
|
||||
Also note that using TypeScript does not fix this problem for you — when libs written in
|
||||
`TypeScript` are used from JS, or when user input ends up there — it behaves exactly as pure JS, as
|
||||
all type checks are translation-time only and are not present in the actual JS code which TS
|
||||
compiles to.
|
||||
|
||||
### Buffer(number)
|
||||
|
||||
For Node.js 0.10.x (and below) support:
|
||||
|
||||
```js
|
||||
var buf;
|
||||
if (Buffer.alloc) {
|
||||
buf = Buffer.alloc(number);
|
||||
} else {
|
||||
buf = new Buffer(number);
|
||||
buf.fill(0);
|
||||
}
|
||||
```
|
||||
|
||||
Otherwise (Node.js ≥ 0.12.x):
|
||||
|
||||
```js
|
||||
const buf = Buffer.alloc ? Buffer.alloc(number) : new Buffer(number).fill(0);
|
||||
```
|
||||
|
||||
## Regarding Buffer.allocUnsafe
|
||||
|
||||
Be extra cautious when using `Buffer.allocUnsafe`:
|
||||
* Don't use it if you don't have a good reason to
|
||||
* e.g. you probably won't ever see a performance difference for small buffers, in fact, those
|
||||
might be even faster with `Buffer.alloc()`,
|
||||
* if your code is not in the hot code path — you also probably won't notice a difference,
|
||||
* keep in mind that zero-filling minimizes the potential risks.
|
||||
* If you use it, make sure that you never return the buffer in a partially-filled state,
|
||||
* if you are writing to it sequentially — always truncate it to the actuall written length
|
||||
|
||||
Errors in handling buffers allocated with `Buffer.allocUnsafe` could result in various issues,
|
||||
ranged from undefined behaviour of your code to sensitive data (user input, passwords, certs)
|
||||
leaking to the remote attacker.
|
||||
|
||||
_Note that the same applies to `new Buffer` usage without zero-filling, depending on the Node.js
|
||||
version (and lacking type checks also adds DoS to the list of potential problems)._

## FAQ

|
||||
### What is wrong with the `Buffer` constructor?
|
||||
|
||||
The `Buffer` constructor could be used to create a buffer in many different ways:
|
||||
|
||||
- `new Buffer(42)` creates a `Buffer` of 42 bytes. Before Node.js 8, this buffer contained
|
||||
*arbitrary memory* for performance reasons, which could include anything ranging from
|
||||
program source code to passwords and encryption keys.
|
||||
- `new Buffer('abc')` creates a `Buffer` that contains the UTF-8-encoded version of
|
||||
the string `'abc'`. A second argument could specify another encoding: For example,
|
||||
`new Buffer(string, 'base64')` could be used to convert a Base64 string into the original
|
||||
sequence of bytes that it represents.
|
||||
- There are several other combinations of arguments.
|
||||
|
||||
This meant that, in code like `var buffer = new Buffer(foo);`, *it is not possible to tell
|
||||
what exactly the contents of the generated buffer are* without knowing the type of `foo`.
|
||||
|
||||
Sometimes, the value of `foo` comes from an external source. For example, this function
|
||||
could be exposed as a service on a web server, converting a UTF-8 string into its Base64 form:
|
||||
|
||||
```
|
||||
function stringToBase64(req, res) {
|
||||
// The request body should have the format of `{ string: 'foobar' }`
|
||||
const rawBytes = new Buffer(req.body.string)
|
||||
const encoded = rawBytes.toString('base64')
|
||||
res.end({ encoded: encoded })
|
||||
}
|
||||
```
|
||||
|
||||
Note that this code does *not* validate the type of `req.body.string`:
|
||||
|
||||
- `req.body.string` is expected to be a string. If this is the case, all goes well.
|
||||
- `req.body.string` is controlled by the client that sends the request.
|
||||
- If `req.body.string` is the *number* `50`, the `rawBytes` would be 50 bytes:
|
||||
- Before Node.js 8, the content would be uninitialized
|
||||
- After Node.js 8, the content would be `50` bytes with the value `0`
|
||||
|
||||
Because of the missing type check, an attacker could intentionally send a number
|
||||
as part of the request. Using this, they can either:
|
||||
|
||||
- Read uninitialized memory. This **will** leak passwords, encryption keys and other
|
||||
kinds of sensitive information. (Information leak)
|
||||
- Force the program to allocate a large amount of memory. For example, when specifying
|
||||
`500000000` as the input value, each request will allocate 500MB of memory.
|
||||
This can be used to either exhaust the memory available of a program completely
|
||||
and make it crash, or slow it down significantly. (Denial of Service)
|
||||
|
||||
Both of these scenarios are considered serious security issues in a real-world
|
||||
web server context.
|
||||
|
||||
when using `Buffer.from(req.body.string)` instead, passing a number will always
|
||||
throw an exception instead, giving a controlled behaviour that can always be
|
||||
handled by the program.
|
||||
|
||||

|
||||
### The `Buffer()` constructor has been deprecated for a while. Is this really an issue?
|
||||
|
||||
Surveys of code in the `npm` ecosystem have shown that the `Buffer()` constructor is still
|
||||
widely used. This includes new code, and overall usage of such code has actually been
|
||||
*increasing*.

|
||||
|
||||
Modern Buffer API polyfill without footguns, working on Node.js from 0.8 to current.
|
||||
|
||||
## How to use?
|
||||
|
||||
First, port all `Buffer()` and `new Buffer()` calls to `Buffer.alloc()` and `Buffer.from()` API.
|
||||
|
||||
Then, to achieve compatibility with outdated Node.js versions (`<4.5.0` and 5.x `<5.9.0`), use
|
||||
`const Buffer = require('safer-buffer').Buffer` in all files where you make calls to the new
|
||||
Buffer API. _Use `var` instead of `const` if you need that for your Node.js version range support._
|
||||
|
||||
Also, see the
|
||||
[porting Buffer](https://github.com/ChALkeR/safer-buffer/blob/master/Porting-Buffer.md) guide.
|
||||
|
||||
## Do I need it?
|
||||
|
||||
Hopefully, not — dropping support for outdated Node.js versions should be fine nowdays, and that
|
||||
is the recommended path forward. You _do_ need to port to the `Buffer.alloc()` and `Buffer.from()`
|
||||
though.
|
||||
|
||||
See the [porting guide](https://github.com/ChALkeR/safer-buffer/blob/master/Porting-Buffer.md)
|
||||
for a better description.
|
||||
|
||||
## Why not [safe-buffer](https://npmjs.com/safe-buffer)?
|
||||
|
||||
_In short: while `safe-buffer` serves as a polyfill for the new API, it allows old API usage and
|
||||
itself contains footguns._
|
||||
|
||||
`safe-buffer` could be used safely to get the new API while still keeping support for older
|
||||
Node.js versions (like this module), but while analyzing ecosystem usage of the old Buffer API
|
||||
I found out that `safe-buffer` is itself causing problems in some cases.
|
||||
|
||||
For example, consider the following snippet:
|
||||
|
||||
```console
|
||||
$ cat example.unsafe.js
|
||||
console.log(Buffer(20))
|
||||
$ ./node-v6.13.0-linux-x64/bin/node example.unsafe.js
|
||||
<Buffer 0a 00 00 00 00 00 00 00 28 13 de 02 00 00 00 00 05 00 00 00>
|
||||
$ standard example.unsafe.js
|
||||
standard: Use JavaScript Standard Style (https://standardjs.com)
|
||||
/home/chalker/repo/safer-buffer/example.unsafe.js:2:13: 'Buffer()' was deprecated since v6. Use 'Buffer.alloc()' or 'Buffer.from()' (use 'https://www.npmjs.com/package/safe-buffer' for '<4.5.0') instead.
|
||||
```
|
||||
|
||||
This is allocates and writes to console an uninitialized chunk of memory.
|
||||
[standard](https://www.npmjs.com/package/standard) linter (among others) catch that and warn people
|
||||
to avoid using unsafe API.
|
||||
|
||||
Let's now throw in `safe-buffer`!
|
||||
|
||||
```console
|
||||
$ cat example.safe-buffer.js
|
||||
const Buffer = require('safe-buffer').Buffer
|
||||
console.log(Buffer(20))
|
||||
$ standard example.safe-buffer.js
|
||||
$ ./node-v6.13.0-linux-x64/bin/node example.safe-buffer.js
|
||||
<Buffer 08 00 00 00 00 00 00 00 28 58 01 82 fe 7f 00 00 00 00 00 00>
|
||||
```
|
||||
|
||||
See the problem? Adding in `safe-buffer` _magically removes the lint warning_, but the behavior
|
||||
remains identiсal to what we had before, and when launched on Node.js 6.x LTS — this dumps out
|
||||
chunks of uninitialized memory.
|
||||
_And this code will still emit runtime warnings on Node.js 10.x and above._
|
||||
|
||||
That was done by design. I first considered changing `safe-buffer`, prohibiting old API usage or
|
||||
emitting warnings on it, but that significantly diverges from `safe-buffer` design. After some
|
||||
discussion, it was decided to move my approach into a separate package, and _this is that separate
|
||||
package_.
|
||||
|
||||
This footgun is not imaginary — I observed top-downloaded packages doing that kind of thing,
|
||||
«fixing» the lint warning by blindly including `safe-buffer` without any actual changes.
|
||||
|
||||
Also in some cases, even if the API _was_ migrated to use of safe Buffer API — a random pull request
|
||||
can bring unsafe Buffer API usage back to the codebase by adding new calls — and that could go
|
||||
unnoticed even if you have a linter prohibiting that (becase of the reason stated above), and even
|
||||
pass CI. _I also observed that being done in popular packages._
|
||||
|
||||
Some examples:
|
||||
* [webdriverio](https://github.com/webdriverio/webdriverio/commit/05cbd3167c12e4930f09ef7cf93b127ba4effae4#diff-124380949022817b90b622871837d56cR31)
|
||||
(a module with 548 759 downloads/month),
|
||||
* [websocket-stream](https://github.com/maxogden/websocket-stream/commit/c9312bd24d08271687d76da0fe3c83493871cf61)
|
||||
(218 288 d/m, fix in [maxogden/websocket-stream#142](https://github.com/maxogden/websocket-stream/pull/142)),
|
||||
* [node-serialport](https://github.com/node-serialport/node-serialport/commit/e8d9d2b16c664224920ce1c895199b1ce2def48c)
|
||||
(113 138 d/m, fix in [node-serialport/node-serialport#1510](https://github.com/node-serialport/node-serialport/pull/1510)),
|
||||
* [karma](https://github.com/karma-runner/karma/commit/3d94b8cf18c695104ca195334dc75ff054c74eec)
|
||||
(3 973 193 d/m, fix in [karma-runner/karma#2947](https://github.com/karma-runner/karma/pull/2947)),
|
||||
* [spdy-transport](https://github.com/spdy-http2/spdy-transport/commit/5375ac33f4a62a4f65bcfc2827447d42a5dbe8b1)
|
||||
(5 970 727 d/m, fix in [spdy-http2/spdy-transport#53](https://github.com/spdy-http2/spdy-transport/pull/53)).
|
||||
* And there are a lot more over the ecosystem.
|
||||
|
||||
I filed a PR at
|
||||
[mysticatea/eslint-plugin-node#110](https://github.com/mysticatea/eslint-plugin-node/pull/110) to
|
||||
partially fix that (for cases when that lint rule is used), but it is a semver-major change for
|
||||
linter rules and presets, so it would take significant time for that to reach actual setups.
|
||||
_It also hasn't been released yet (2018-03-20)._
|
||||
|
||||
Also, `safer-buffer` discourages the usage of `.allocUnsafe()`, which is often done by a mistake.
|
||||
It still supports it with an explicit concern barier, by placing it under
|
||||
`require('safer-buffer/dangereous')`.
|
||||
|
||||
## But isn't throwing bad?
|
||||
|
||||
Not really. It's an error that could be noticed and fixed early, instead of causing havoc later like
|
||||
unguarded `new Buffer()` calls that end up receiving user input can do.
|
||||
|
||||
This package affects only the files where `var Buffer = require('safer-buffer').Buffer` was done, so
|
||||
it is really simple to keep track of things and make sure that you don't mix old API usage with that.
|
||||
Also, CI should hint anything that you might have missed.
|
||||
|
||||
New commits, if tested, won't land new usage of unsafe Buffer API this way.
|
||||
_Node.js 10.x also deals with that by printing a runtime depecation warning._
|
||||
|
||||
### Would it affect third-party modules?
|
||||
|
||||
No, unless you explicitly do an awful thing like monkey-patching or overriding the built-in `Buffer`.
|
||||
Don't do that.
|
||||
|
||||
### But I don't want throwing…
|
||||
|
||||
That is also fine!
|
||||
|
||||
Also, it could be better in some cases when you don't comprehensive enough test coverage.
|
||||
|
||||
In that case — just don't override `Buffer` and use
|
||||
`var SaferBuffer = require('safer-buffer').Buffer` instead.
|
||||
|
||||
That way, everything using `Buffer` natively would still work, but there would be two drawbacks:
|
||||
|
||||
* `Buffer.from`/`Buffer.alloc` won't be polyfilled — use `SaferBuffer.from` and
|
||||
`SaferBuffer.alloc` instead.
|
||||
* You are still open to accidentally using the insecure deprecated API — use a linter to catch that.
|
||||
|
||||
Note that using a linter to catch accidential `Buffer` constructor usage in this case is strongly
|
||||
recommended. `Buffer` is not overriden in this usecase, so linters won't get confused.
|
||||
|
||||
## «Without footguns»?
|
||||
|
||||
Well, it is still possible to do _some_ things with `Buffer` API, e.g. accessing `.buffer` property
|
||||
on older versions and duping things from there. You shouldn't do that in your code, probabably.
|
||||
|
||||
The intention is to remove the most significant footguns that affect lots of packages in the
|
||||
ecosystem, and to do it in the proper way.
|
||||
|
||||
Also, this package doesn't protect against security issues affecting some Node.js versions, so for
|
||||
usage in your own production code, it is still recommended to update to a Node.js version
|
||||
[supported by upstream](https://github.com/nodejs/release#release-schedule).
