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.
