Description Hanno Böck gentoo-dev 2014-07-17 07:29:53 UTC
A race condition in apache's mod_status can lead to a buffer overflow.
Fix is in upstream's apache 2.4.10 which is not yet released but a pre-release package is available and release should be ready within the next days:

I don't know about the status in apache 2.2.

Seems to be fixed in 2.2.28, but also not released yet:
Comment 2 Hanno Böck gentoo-dev 2014-07-21 22:56:51 UTC
Finally apache 2.4.10 has been released. 2.2.28 not yet.

CVE-2014-0226 (
  Race condition in the mod_status module in the Apache HTTP Server before
  2.4.10 allows remote attackers to cause a denial of service (heap-based
  buffer overflow), or possibly obtain sensitive credential information or
  execute arbitrary code, via a crafted request that triggers improper
  scoreboard handling within the status_handler function in
  modules/generators/mod_status.c and the lua_ap_scoreboard_worker function in
Comment 4 Patrick Lauer gentoo-dev 2014-07-24 02:30:32 UTC
Ebuilds for 2.4.10 have been committed
Comment 5 Yury German Gentoo Infrastructure gentoo-dev 2014-07-26 04:03:52 UTC
Maintainer(s): please let us know when the ebuild is ready for  stabilization.

Unfortunately not yet. Patrick added the ebuilds without my permission omitting all the changes I wanted to incorporate in a new patchset. So please wait for apache-2.4.10-r1.
Comment 7 Yury German Gentoo Infrastructure gentoo-dev 2014-07-27 19:16:10 UTC
Please advise or call for stabilization when ready.

I've added apache-2.2.27-r4 which fixes the following security bugs:
CVE-2014-0118, CVE-2014-0226 and CVE-2014-0231
apache-2.4.x still isn't stable and I prefer to not stbilize it yet.

Stabilized www-servers/apache-2.2.27-r4 on alpha.
Comment 10 Yury German Gentoo Infrastructure gentoo-dev 2014-07-31 17:48:34 UTC

Please do not close bug at the end, we will wait for apache-2.4.x to stabilize.
