squid security update
Security Advisory: Moderate
Updated squid packages that fix a denial of service issue are now available.
This update has been rated as having important security impact by the Red
Hat Security Response Team
Squid is a full-featured Web proxy cache.
A bug was found in the way Squid handles FQDN lookups. It was possible
to crash the Squid server by sending a carefully crafted DNS response to
an FQDN lookup. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2005-0446 to this issue.
Users of squid should upgrade to this updated package, which contains a
backported patch, and is not vulnerable to this issue.
