CentOS Errata and Security Advisory CESA-2006:0159

The Apache HTTP Server is a popular and freely-available Web server.

A memory leak in the worker MPM could allow remote attackers to cause a
denial of service (memory consumption) via aborted connections, which
prevents the memory for the transaction pool from being reused for other
connections. The Common Vulnerabilities and Exposures project assigned the
name CVE-2005-2970 to this issue. This vulnerability only affects users
who are using the non-default worker MPM.

A flaw in mod_imap when using the Referer directive with image maps was
discovered. With certain site configurations, a remote attacker could
perform a cross-site scripting attack if a victim can be forced to visit a
malicious URL using certain web browsers. (CVE-2005-3352)

A NULL pointer dereference flaw in mod_ssl was discovered affecting server
configurations where an SSL virtual host is configured with access control
and a custom 400 error document. A remote attacker could send a carefully
crafted request to trigger this issue which would lead to a crash. This
crash would only be a denial of service if using the non-default worker
MPM. (CVE-2005-3357)

Users of httpd should update to these erratum packages which contain
backported patches to correct these issues along with some additional bugs.
