Synopsis
========
A buffer overflow in Apache mod_fcgid might allow remote attackers to
execute arbitrary code or cause a Denial of Service condition.

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

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apache/mod_fcgid < 2.3.9 >= 2.3.9

Description
===========
Apache mod_fcgid fails to perform a boundary check on user-supplied
input, potentially resulting in a heap-based buffer overflow.

Impact
======
A remote attacker can supply a crafted input, possibly resulting in
execution of arbitrary code or a Denial of Service condition.

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

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

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apache/mod_fcgid-2.3.9"

References
