Apache: Multiple vulnerabilities

Background

The Apache HTTP server is one of the most popular web servers on the Internet.

Description

Multiple cross-site scripting vulnerabilities have been discovered in mod_status and mod_autoindex (CVE-2006-5752, CVE-2007-4465). An error has been discovered in the recall_headers() function in mod_mem_cache (CVE-2007-1862). The mod_cache module does not properly sanitize requests before processing them (CVE-2007-1863). The Prefork module does not properly check PID values before sending signals (CVE-2007-3304). The mod_proxy module does not correctly check headers before processing them (CVE-2007-3847).

Impact

A remote attacker could exploit one of these vulnerabilities to inject arbitrary script or HTML content, obtain sensitive information or cause a Denial of Service.

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 ">=www-servers/apache-2.0.59-r5"
