RedHat: Important: squid security update
Summary
Summary
Squid is a full-featured Web proxy cache. A bug was found in the way Squid displays error messages. A remote attacker could submit a request containing an invalid hostname which would result in Squid displaying a previously used error message. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-2479 to this issue. Two denial of service bugs were found in the way Squid handles malformed requests. A remote attacker could submit a specially crafted request to Squid that would cause the server to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2005-2794 and CAN-2005-2796 to these issues. Please note that CAN-2005-2796 does not affect Red Hat Enterprise Linux 2.1 Users of Squid should upgrade to this updated package that contains backported patches, and is not vulnerable to these issues.
