Synopsis
=======

Squirrelmail is vulnerable to several cross-site scripting vulnerabilities which could lead to a compromise of webmail accounts.



Background
=========

SquirrelMail is a webmail package written in PHP. It supports IMAP and SMTP protocols.

Affected packages
================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 mail-client/squirrelmail < 1.4.4 >= 1.4.4
< 1.4.0

Description
==========

SquirrelMail is vulnerable to several cross-site scripting issues, most reported by Martijn Brinkers.

Impact
=====

By enticing a user to read a specially-crafted e-mail or using a manipulated URL, an attacker can execute arbitrary scripts running in the context of the victim's browser. This could lead to a compromise of the user's webmail account, cookie theft, etc.

Workaround
=========

There is no known workaround at this time.

Resolution
=========

All SquirrelMail users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/squirrelmail-1.4.4"

Note: Users with the vhosts USE flag set should manually use webapp-config to finalize the update.
