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.
