Vulnerability Assessment Details

RHSA-2005-201: squid

Vulnerability Assessment Summary
Check for the version of the squid packages

Detailed Explanation for this Vulnerability Assessment

An updated squid package that fixes a denial of service issue is now
available for Red Hat Enterprise Linux 4.

This update has been rated as having moderate 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 fully qualified domain name (FQDN)
lookups. A malicious DNS server could crash Squid by sending a carefully
crafted DNS response to an FQDN lookup. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2005-0446 to
this issue.

This erratum also includes two minor patches to the LDAP helpers. One
corrects a slight malformation in ldap search requests (although all
known LDAP servers accept the requests). The other adds documentation
for the -v option to the ldap helpers.

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