1. Summary:

An updated squirrelmail package that fixes two security issues is now available.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

[Updated 04 Aug 2005]
The previous SquirrelMail package released with this errata contained a bug which rendered the addressbook unusable. The erratum has been updated with a package which corrects this issue.

Red Hat Enterprise Linux AS version 3 - noarch
Red Hat Desktop version 3 - noarch
Red Hat Enterprise Linux ES version 3 - noarch

3. Problem description:

SquirrelMail is a standards-based webmail package written in PHP4.

A bug was found in the way SquirrelMail handled the $_POST variable. If a user is tricked into visiting a malicious URL, the user's SquirrelMail preferences could be read or modified. The Common Vulnerabilities and Exposures project assigned the name CAN-2005-2095 to this issue.

Several cross-site scripting bugs were discovered in SquirrelMail. An attacker could inject arbitrary Javascript or HTML content into SquirrelMail pages by tricking a user into visiting a carefully crafted URL, or by sending them a carefully constructed HTML email message. The Common Vulnerabilities and Exposures project assigned the name CAN-2005-1769 to this issue.

All users of SquirrelMail should upgrade to this updated package, which contains backported patches that resolve these issues.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command:
