Notable changes
* buffer: Fixed a bug introduced in v4.1.0 where allocating a new
zero-length buffer can result in the next allocation of a TypedArray
in JavaScript not being zero-filled. In certain circumstances this
could result in data leakage via reuse of memory space in
TypedArrays, breaking the normally safe assumption that TypedArrays
should be always zero-filled. (Trevor Norris) #2931.
* http: Guard against response-splitting of HTTP trailing headers
added via response.addTrailers() by removing new-line ([\r\n])
characters from values. Note that standard header values are already
stripped of new-line characters. The expected security impact is low
because trailing headers are rarely used. (Ben Noordhuis) #2945.
* npm: Upgrade to npm 2.14.4 from 2.14.3, see release notes for full
details (Kat Marchán) #2958
- Upgrades graceful-fs on multiple dependencies to no longer rely on
monkey-patching fs
- Fix npm link for pre-release / RC builds of Node
* v8: Update post-mortem metadata to allow post-mortem debugging tools
to find and inspect:
- JavaScript objects that use dictionary properties
(Julien Gilli) #2959
- ScopeInfo and thus closures (Julien Gilli) #2974
* **buffer**: Fixed a bug introduced in v4.1.0 where allocating a new zero-length buffer can result in the _next_ allocation of a TypedArray in JavaScript not being zero-filled. In certain circumstances this could result in data leakage via reuse of memory space in TypedArrays, breaking the normally safe assumption that TypedArrays should be always zero-filled. (Trevor Norris) [#2931](https://github.com/nodejs/node/pull/2931).
* **http**: Guard against response-splitting of HTTP trailing headers added via [`response.addTrailers()`](https://nodejs.org/api/http.html#http_response_addtrailers_headers) by removing new-line (`[\r\n]`) characters from values. Note that standard header values are already stripped of new-line characters. The expected security impact is low because trailing headers are rarely used. (Ben Noordhuis) [#2945](https://github.com/nodejs/node/pull/2945).
* **npm**: Upgrade to npm 2.14.4 from 2.14.3, see [release notes](https://github.com/npm/npm/releases/tag/v2.14.4) for full details (Kat Marchán) [#2958](https://github.com/nodejs/node/pull/2958)
- Upgrades `graceful-fs` on multiple dependencies to no longer rely on monkey-patching `fs`
- Fix `npm link` for pre-release / RC builds of Node
* **v8**: Update post-mortem metadata to allow post-mortem debugging tools to find and inspect:
- JavaScript objects that use dictionary properties (Julien Gilli) [#2959](https://github.com/nodejs/node/pull/2959)
