SquirrelMail is a webmail package written in PHP. Multiple vulnerabilities
have been found which affect versions of SquirrelMail shipped with Red Hat
Linux 8.0 and Red Hat Linux 9.
Cross-site scripting vulnerabilities in SquirrelMail version 1.2.10 and
earlier allow remote attackers to execute script as other Web users via
mailbox displays, message displays, or search results displays. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2003-0160 to these issues.
All users are advised to upgrade to these errata packages containing
SquirrelMail version 1.2.11, which is not vulnerable to these issues.
