3. Problem description:

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

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.  (CVE-2006-6142) 

Users of SquirrelMail should upgrade to this erratum package, which
contains a backported patch to correct these issues. 

Notes:
- - - After installing this update, users are advised to restart their
httpd service to ensure that the updated version functions correctly.
- - - config.php should NOT be modified, please modify config_local.php instead.
- - - Known Bug: The configuration generator may potentially produce bad
options that interfere with the operation of this application.  Applying
specific config changes to config_local.php manually is recommended.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
