Details

An updated squid package that fixes a security vulnerability is now
available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Squid is a high-performance proxy caching server for Web clients,
supporting FTP, gopher, and HTTP data objects.

A denial of service flaw was found in the way Squid processed the TRACE
request method. It was possible for an attacker behind the Squid proxy
to issue a malformed TRACE request, crashing the Squid daemon child
process. As long as these requests were sent, it would prevent
legitimate usage of the proxy server. (CVE-2007-1560)

This flaw does not affect the version of Squid shipped in Red Hat
Enterprise Linux 2.1, 3, or 4.

Users of Squid should upgrade to this updated package, which contains a
backported patch and is not vulnerable to this issue.

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
