Topic: An updated SquirrelMail package that fixes several security vulnerabilities is now available. 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 3. Problem description: SquirrelMail is a webmail package written in PHP. Multiple vulnerabilities have been found which affect the version of SquirrelMail shipped with Red Hat Enterprise Linux 3. An SQL injection flaw was found in SquirrelMail version 1.4.2 and earlier. If SquirrelMail is configured to store user addressbooks in the database, a remote attacker could use this flaw to execute arbitrary SQL statements. The Common Vulnerabilities and Exposures project has assigned the name CAN-2004-0521 to this issue. A number of cross-site scripting (XSS) flaws in SquirrelMail version 1.4.2 and earlier could allow remote attackers to execute script as other web users. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2004-0519 and CAN-2004-0520 to these issues. All users of SquirrelMail are advised to upgrade to the erratum package containing SquirrelMail version 1.4.3a which is not vulnerable to these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. 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.
