Updated squirrelmail packages are now available for Red Hat Linux.
SquirrelMail is a webmail package written in PHP. Two vulnerabilities have been found that affect versions of SquirrelMail shipped with Red Hat Linux 8.0. A cross-site scripting (XSS) vulnerability in Squirrelmail version 1.2.10 and earlier allows remote attackers to execute script as other web users via read_body.php. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2002-1341 to this issue. An incomplete fix for a cross-site scripting vulnerability in SquirrelMail 1.2.8 calls the strip_tags function on the PHP_SELF value but does not save the result back to that variable, leaving it open to cross-site scripting attacks. (CAN-2002-1276) All users of Squirrelmail are advised to upgrade to these packages based on SquirrelMail version 1.2.10 which contain a backported patch to fix these issues.
