CentOS 3 / 4 : httpd (CESA-2006:0159)

Medium Nessus Plugin ID 21884

Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated Apache httpd packages that correct three security issues are now available for Red Hat Enterprise Linux 3 and 4.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

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.

Solution

Update the affected httpd packages.
