mod_ssl security update

Synopsis

mod_ssl security update

Type/Severity

Security Advisory: Important

Topic

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

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.
