squirrelmail security update

CentOS Errata and Security Advisory CESA-2007:0022

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.
