Triggered by a report to Packet Storm from Virulent, a format string
vulnerability was found in mod_ssl, the Apache SSL/TLS interface to
OpenSSL, version (up to and including) 2.8.18 for Apache 1.3. The mod_ssl
in Apache 2.x is not affected. The vulnerability could be exploitable if
Apache is used as a proxy for HTTPS URLs and the attacker established a own
specially prepared DNS and origin server environment.
