CVE Names: CAN-2004-0700
----------------------------------------------------------------------

1. Summary:

An updated mod_ssl package for Apache that fixes a format string vulnerability is now available.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64

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 format string issue was discovered in mod_ssl for Apache 1.3 which can be triggered if mod_ssl is configured to allow a client to proxy to remote SSL sites. In order to exploit this issue, a user who is authorized to use Apache as a proxy would have to attempt to connect to a carefully crafted hostname via SSL. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0700 to this issue.

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

4. Solution:
