A heap overflow was found, I don't have further details, but please provide an updated ebuild, it's a remotely exploitable bug.

Thanks hollow.

Arches, please test and mark stable:
=www-servers/nginx-1.0.10
Target keywords : "amd64 x86"
Comment 6 Agostino Sarubbo gentoo-dev 2011-11-20 10:02:21 UTC
Fine for me on both arches.
Comment 7 Michael Harrison 2011-11-22 09:53:32 UTC
amd64 ok; compilation, startup, and nginix -t tests all good
Comment 8 Michael Harrison 2011-11-22 10:00:03 UTC
forgot to make note that USE="passenger" returned
Passenger support has been removed from the nginx ebuild to
 
* get rid of file collisions, its broken build system and
 * incompatibilities between passenger 2 and 3.
 * 
 * Please switch to passenger-3 standalone or use the
 * unicorn gem which provides a sane nginx-like architecture
 * out of the box.

switched to passenger-3 and all went fine as stated above.

+  22 Nov 2011; Tony Vroon <chainsaw@gentoo.org> nginx-1.0.10.ebuild:
+  Marked stable on AMD64 based on arch testing by Agostino "ago" Sarubbo &
+  Michael "n0idx80" Harrison in security bug #389319.

Security, that's stable keywording complete for all arches.

  via a long response.
