(RHSA-2007:0131) Moderate: squid security update

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.
