RHEL 2.1 : mod_ssl (RHSA-2005:773)

critical Nessus Plugin ID 19714

Synopsis

The remote Red Hat host is missing a security update.

Description

An updated mod_ssl package for Apache that corrects a security issue is now available.

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

The mod_ssl module provides strong cryptography for the Apache Web server via the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols.

A flaw was discovered in mod_ssl's handling of the 'SSLVerifyClient' directive. This flaw occurs if a virtual host is configured using 'SSLVerifyClient optional' and a directive 'SSLVerifyClient required' is set for a specific location. For servers configured in this fashion, an attacker may be able to access resources that should otherwise be protected, by not supplying a client certificate when connecting. The Common Vulnerabilities and Exposures project assigned the name CVE-2005-2700 to this issue.

Users of mod_ssl should upgrade to this updated package, which contains a backported patch to correct this issue.

Solution

Update the affected mod_ssl package.
