Medium Nessus Plugin ID 21363


The remote Red Hat host is missing a security update.


An updated squirrelmail package that fixes three security and many other bug issues is now available. This update contains bug fixes of upstream squirrelmail 1.4.6 with some additional improvements to international language support.

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.

A bug was found in the way SquirrelMail presents the right frame to the user. If a user can be tricked into opening a carefully crafted URL, it is possible to present the user with arbitrary HTML data.

A bug was found in the way SquirrelMail filters incoming HTML email.
It is possible to cause a victim's web browser to request remote content by opening a HTML email while running a web browser that processes certain types of invalid style sheets. Only Internet Explorer is known to process such malformed style sheets.

A bug was found in the way SquirrelMail processes a request to select an IMAP mailbox. If a user can be tricked into opening a carefully crafted URL, it is possible to execute arbitrary IMAP commands as the user viewing their mail with SquirrelMail. (CVE-2006-0377)

Users of SquirrelMail are advised to upgrade to this updated package, which contains SquirrelMail version 1.4.6 and is not vulnerable to these issues.


Update the affected squirrelmail package.
