RedHat: Low: squid security update
Summary
Summary
Squid is a full-featured Web proxy cache. A race condition bug was found in the way Squid handles the now obsolete Set-Cookie header. It is possible that Squid can leak Set-Cookie header information to other clients connecting to Squid. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0626 to this issue. Please note that this issue only affected Red Hat Enterprise Linux 4. A bug was found in the way Squid handles PUT and POST requests. It is possible for an authorised remote user to cause a failed PUT or POST request which can cause Squid to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0718 to this issue. A bug was found in the way Squid processes errors in the access control list. It is possible that an error in the access control list could give users more access than intended. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1345 to this issue. A bug was found in the way Squid handles access to the cachemgr.cgi script. It is possible for an authorised remote user to bypass access control lists with this flaw. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-1999-0710 to this issue. A bug was found in the way Squid handles DNS replies. If the port Squid uses for DNS requests is not protected by a firewall it is possible for a remote attacker to spoof DNS replies, possibly redirecting a user to spoofed or malicious content. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1519 to this issue. Additionally this update fixes the following bugs: - LDAP Authentication fails with an assertion error when using Red Hat Enterprise Linux 4 Users of Squid should upgrade to this updated package, which contains backported patches to correct these issues.
