Synopsis
========
Multiple vulnerabilities have been found in mod_fcgid, allowing
execution of arbitrary code or Denial of Service.

Background
==========
mod_fcgid is a binary-compatible alternative to mod_fastcgi with better
process management.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apache/mod_fcgid < 2.3.7 >= 2.3.7

Description
===========
Multiple vulnerabilities have been found in mod_fcgid:

* An error in the "fcgid_header_bucket_read()" function in
fcgid_bucket.c could cause a stack-based buffer overflow
(CVE-2010-3872).
* An error in the "is_spawn_allowed() function in fcgid_spawn_ctl.c
prevents Apache from recognizing the FcgidMaxProcessesPerClass
directive for a virtual host (CVE-2012-1181).

Impact
======
A local attacker could possibly execute arbitrary code with the
privileges of the process or cause a Denial of Service condition.
Furthermore, a remote attacker could send specially crafted HTTP
requests, possibly resulting in a Denial of Service condition.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All mod_fcgid users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apache/mod_fcgid-2.3.7"
