Node v4.1.1 (Current)

Rod Vagg

This release contains some minor security-related updates. You are advised to upgrade to 4.1.1 if you are currently running v4.1.0.

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
