Summary
Red Hat Security Advisory: mod_ssl security update

Notes

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