RedHat: Moderate: squid security update RHSA-2006:0045-01
Summary
Summary
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 processes certain NTLM authentication requests. A remote attacker could send a specially crafted NTLM authentication request which would cause the Squid server to crash. The Common Vulnerabilities and Exposures project assigned the name CVE-2005-2917 to this issue. Several bugs have also been addressed in this update: * An error introduced in 2.5.STABLE3-6.3E.14 where Squid can crash if a user visits a site which has a long DNS record. * Some authentication helpers were missing needed setuid rights. * Squid couldn't handle a reply from a HTTP server when the reply began with the new-line character or wasn't HTTP/1.0 or HTTP/1.1 compliant. * User-defined error pages were not kept when the squid package was upgraded. All users of squid should upgrade to these updated packages, which contain backported patches to resolve these issues.
