RHEL 3 / 4 / 5 : squirrelmail (RHSA-2007:0358)
Medium Nessus Plugin ID 25270
SynopsisThe remote Red Hat host is missing a security update.
DescriptionA new squirrelmail package that fixes security issues is now available for Red Hat Enterprise Linux 3, 4 and 5.
This update has been rated as having moderate security impact by the Red Hat Security Response Team.
SquirrelMail is a standards-based webmail package written in PHP4.
Squirrelmail did not sufficiently check arguments to IMG tags in HTML e-mail messages. This could be exploited by an attacker by sending arbitrary e-mail messages on behalf of a squirrelmail user tricked into opening a maliciously crafted HTML e-mail message.
Users of SquirrelMail should upgrade to this erratum package, which contains a backported patch to correct these issues.
SolutionUpdate the affected squirrelmail package.
