Synopsis

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

2. Impact Information

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).

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.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All Apache users should upgrade to the latest version:

Code Listing 3.1: Resolution
