Detail
| Problem Description: Updated squid packages that fix a security vulnerability as well as several bugs are now available. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 3. Problem description: 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. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command: up2date For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system: http://www.redhat.com/docs/manuals/enterprise/ 5. Bug IDs fixed (http://bugzilla.redhat.com/): 127836 - Error pages should not be replaced by updates 150781 - Squid doesn't handle headers split across packets 163595 - Squid blocks page served by broken server 165367 - Squid dies with signal 6 and restarts and dies ... 169269 - Error in script /usr/lib/squid/wbinfo_group.pl 170397 - pam authentication fails 172693 - One translated Polish language error is missing preventing squid from startup 174029 - CVE-2005-2917 Squid malformed NTLM authentication DoS |
