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"
