Ubuntu 4.10 / 5.04 : apache2 vulnerabilities (USN-160-1)

medium Nessus Plugin ID 20565

Synopsis

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

Description

Marc Stern discovered a buffer overflow in the SSL module's certificate revocation list (CRL) handler. If Apache is configured to use a malicious CRL, this could possibly lead to a server crash or arbitrary code execution with the privileges of the Apache web server.
(CAN-2005-1268)

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.
(CAN-2005-2088).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
