- --------------------------------------------------------------------- Red Hat Security Advisory
Synopsis: Important: mod_ssl security update Advisory ID: RHSA-2005:773-01 Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-773.html Issue date: 2005-09-15 Updated on: 2005-09-15 Product: Red Hat Enterprise Linux CVE Names: CAN-2005-2700 - ---------------------------------------------------------------------
1. Summary:
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.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386
3. Problem description:
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 CAN-2005-2700 to this issue.
Users of mod_ssl should upgrade to this updated package, which contains a backported patch to correct this issue.
4. Solution:
Before applying this update, make sure all previously released errata relevant to your system have been applied.
This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.
