Summary: Updated mailman packages that correct a mailman security issue are now available. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 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: The mailman package is software to help manage email discussion lists. A flaw in the true_path function of Mailman was discovered. A remote attacker who is a member of a private mailman list could use a carefully crafted URL and gain access to arbitrary files on the server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0202 to this issue. Note: Mailman installations running on Apache 2.0-based servers are not vulnerable to this issue. Users of mailman should update to these erratum packages that contain a patch and are 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.
