Summary: An updated squirrelmail package that fixes a local file disclosure flaw is 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 - noarch Red Hat Desktop version 3 - noarch Red Hat Enterprise Linux ES version 3 - noarch Red Hat Enterprise Linux WS version 3 - noarch Red Hat Enterprise Linux AS version 4 - noarch Red Hat Enterprise Linux Desktop version 4 - noarch Red Hat Enterprise Linux ES version 4 - noarch Red Hat Enterprise Linux WS version 4 - noarch 3. Problem description: SquirrelMail is a standards-based webmail package written in PHP4. A local file disclosure flaw was found in the way SquirrelMail loads plugins. In SquirrelMail 1.4.6 or earlier, if register_globals is on and magic_quotes_gpc is off, it became possible for an unauthenticated remote user to view the contents of arbitrary local files the web server has read-access to. This configuration is neither default nor safe, and configuring PHP with the register_globals set on is dangerous and not recommended. (CVE-2006-2842) Users of SquirrelMail should upgrade to this erratum package, which contains a backported patch to correct this issue. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5.
