Apache < 2.0.51 Multiple Vulnerabilities (OF, DoS)

This script is Copyright (C) 2004-2012 Tenable Network Security, Inc.


Synopsis :

The remote web server is affected by multiple vulnerabilities.

Description :

According to its Server response header, the remote host is running a
version of Apache 2.0 that is older than 2.0.51. Such versions may be
affected by several issues, including :

- An input validation issue in apr-util can be triggered
by malformed IPv6 literal addresses and result in a
buffer overflow (CVE-2004-0786).

- There is a buffer overflow that can be triggered when
expanding environment variables during configuration
file parsing (CVE-2004-0747).

- A segfault in mod_dav_ds when handling an indirect lock
refresh can lead to a process crash (CVE-2004-0809).

- A segfault in the SSL input filter can be triggered
if using 'speculative' mode by, for instance, a proxy
request to an SSL server (CVE-2004-0751).

- There is the potential for an infinite loop in mod_ssl
(CVE-2004-0748).
