Synopsis
========

A buffer overflow vulnerability exists in mod_include which could
possibly allow a local attacker to gain escalated privileges.

Background
==========

The Apache HTTP server is one of the most popular web servers on the
internet. mod_include is an Apache module to handle Server Side
Includes (SSI).

Affected packages
=================

     -------------------------------------------------------------------
      Package         /   Vulnerable   /                     Unaffected
     -------------------------------------------------------------------
   1  net-www/apache      < 1.3.32-r1                      >= 1.3.32-r1

Description
===========

A possible buffer overflow exists in the get_tag() function of
mod_include.c.

Impact
======

If Server Side Includes (SSI) are enabled, a local attacker may be able
to run arbitrary code with the rights of an httpd child process by
making use of a specially-crafted document with malformed SSI.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Apache users should upgrade to the latest version:

     # emerge --sync
     # emerge --ask --oneshot --verbose ">=net-www/apache-1.3.32-r1"
