Description Johan Bergström 2014-03-18 20:53:39 UTC
A bug in the experimental SPDY implementation in nginx was found, which might allow an attacker to cause a heap memory buffer overflow in a worker process by using a specially crafted request, potentially resulting in arbitrary code execution (CVE-2014-0133). Patch is trivial, but I suggest we bump to 1.4.7 as soon as possible. 1.5.x (in tree, masked) is vulnerable as well. Patch here: http://nginx.org/download/patch.2014.spdy2.txt
Comment 1 Alex Xu (Hello71) 2014-03-18 21:40:07 UTC
I think it is plausible that at least 5% of Gentoo users have nginx installed. However, USE=debug is likely highly rare. Perhaps C1 is more appropriate.
Comment 2 Johan Bergström 2014-03-18 21:46:59 UTC
@Alex: The bug will occur if you've built the spdy module without debug.
Comment 3 Alex Xu (Hello71) 2014-03-18 21:50:56 UTC
Odd, I swear I read "with --with-debug". Never mind then, definitely B1. Not A1 though, spdy is far from default.

nginx-1.4.7 is now in the tree for stabilization, 1.5.12 follows...

CVE-2014-0133 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-0133): Heap-based buffer overflow in the SPDY implementation in nginx 1.3.15 before 1.4.7 and 1.5.x before 1.5.12 allows remote attackers to execute arbitrary code via a crafted request.
