From https://bugzilla.redhat.com/show_bug.cgi?id=1306203:

It was reported that HTTP header parsing in Node.js is vulnerable to response splitting attacks. While Node.js has been protecting against response splitting attacks by checking for CRLF characters, it is possible to compose response headers using Unicode 
characters that decompose to these characters, bypassing the checks previously in place.

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

Update from maintainer (by proxy):

One of these vulnerabilities actually lives in net-libs/http-parser which was bumped to 2.6.1 Yesterday.

net-libs/nodejs-5.6.0 is work in progress; an ebuild sent for review (to proxies) available here: https://github.com/gentoo/gentoo/pull/781

"Unfortunately" we also have to bump 0.10, 0.12, and the LTS 4.x series. I will be reviewing these ebuilds the coming days. http-parser might not be releasing stable series for each of these so I will have to review that it works as intended before we bump.

If anyone wants more information about these vulnerabilities, feel free to contact me privately.

[Comment 2 Patrick Lauer 2016-02-11 12:08:48 UTC]

ebuild for both http-parser-2.6.1 and nodejs-5.6.0 are in tree.

[Comment 3 Pacho Ramos 2016-05-17 15:16:50 UTC]

Does 4.4.1 fix this? (it should be stabilized in bug 568900 it seems)

[Comment 4 Thomas Deutschmann (RETIRED) 2016-11-29 21:26:35 UTC]

@ Arches,

please test and mark stable: =net-libs/nodejs-0.12.10

CVE-2016-2216 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2016-2216):
  The HTTP header parsing code in Node.js 0.10.x before 0.10.42, 0.11.6
  through 0.11.16, 0.12.x before 0.12.10, 4.x before 4.3.0, and 5.x before
  5.6.0 allows remote attackers to bypass an HTTP response-splitting
  protection mechanism via UTF-8 encoded Unicode characters in the HTTP
  header, as demonstrated by %c4%8d%c4%8a.

CVE-2016-2086 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2016-2086):
  Node.js 0.10.x before 0.10.42, 0.12.x before 0.12.10, 4.x before 4.3.0, and
  5.x before 5.6.0 allow remote attackers to conduct HTTP request smuggling
  attacks via a crafted Content-Length HTTP header.

Proxy-maint package... tree is clean:
