Detail
| Problem Description: An updated squid package that fixes a security vulnerability in the NTLM authentication helper is now available. 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 full-featured Web proxy cache. An out of bounds memory read bug was found within the NTLM authentication helper routine. If Squid is configured to use the NTLM authentication helper, a remote attacker could send a carefully crafted NTLM authentication packet and cause Squid to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0832 to this issue. Note: The NTLM authentication helper is not enabled by default in Red Hat Enterprise Linux 3. Red Hat Enterprise Linux 2.1 is not vulnerable to this issue as it shipped with a version of Squid which did not contain the vulnerable helper. Users of Squid should update to this erratum package, which contains a backported patch and is not vulnerable to this issue. 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/ for more info): 131750 - CAN-2004-0832 Certain malformed NTLMSSP packets could crash the NTLM helpers provided by Squid |
