A bug in mod_ssl may allow a remote attacker to execute arbitrary code when Apache is configured to use mod_ssl and mod_proxy.
mod_ssl provides Secure Sockets Layer encryption and authentication to Apache 1.3.
A bug in ssl_engine_ext.c makes mod_ssl vulnerable to a ssl_log() related format string vulnerability in the mod_proxy hook functions.
Given the right server configuration, an attacker could execute code as the user running Apache, usually "apache".
A server should not be vulnerable if it is not using both mod_ssl and mod_proxy. Otherwise there is no workaround other than to disable mod_ssl.
All mod_ssl users should upgrade to the latest version:
