Topic: An updated SquirrelMail package that fixes a cross-site scripting vulnerability is now available. SquirrelMail is a webmail package written in PHP. 2. Relevant releases/architectures: Red Hat Linux 9 - i386 Fedora Core 1 - i386 3. Problem description: A cross-site scripting bug has been found in SquirrelMail. This issue could allow an attacker to send a mail with a carefully crafted header, which could result in causing the victim's machine to execute a malicious script. The Common Vulnerabilities and Exposures project has assigned the name CAN-2004-1036 to this issue. Jimmy Conner discovered a missing variable initialization in Squirrelmail. This flaw could allow potential insecure file inclusions on servers where the PHP setting "register_globals" is set to "On". This is not a default or recommended setting. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0075 to this issue. A URL sanitisation bug was found in Squirrelmail. This flaw could allow a cross site scripting attack when loading the URL for the sidebar. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0103 to this issue. A missing variable initialization bug was found in Squirrelmail. This flaw could allow a cross site scripting attack. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0104 to this issue. Users of Squirrelmail are advised to upgrade to this updated package, which contains backported patches to correct 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 yum and apt. Many people find this an easier way to apply updates. To use yum issue: yum update or to use apt: apt-get update; apt-get upgrade This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www.fedoralegacy.org/docs for directions on how to configure yum and apt-get. 5.
