Ubuntu 4.10 / 5.04 : apache vulnerability (USN-160-2)

Ubuntu Security Notice (C) 2005-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.

Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

USN-160-1 fixed two vulnerabilities in the Apache 2 server. The old
Apache 1 server was also vulnerable to one of the vulnerabilities
(CAN-2005-2088). Please note that Apache 1 is not officially supported
in Ubuntu (it is in the 'universe' component of the archive).

For reference, this is the relevant part of the original advisory :

Watchfire discovered that Apache insufficiently verified the
'Transfer-Encoding' and 'Content-Length' headers when acting as an
HTTP proxy. By sending a specially crafted HTTP request, a remote
attacker who is authorized to use the proxy could exploit this to
bypass web application firewalls, poison the HTTP proxy cache, and
conduct cross-site scripting attacks against other proxy users.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 4.3
