Synopsis
========

Squirrelmail fails to properly sanitize user input, which could lead to
a compromise of webmail accounts.

Background
==========

SquirrelMail is a webmail package written in PHP. It supports IMAP and
SMTP, and can optionally be installed with SQL support.

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

    -------------------------------------------------------------------
     Package                   /   Vulnerable   /           Unaffected
    -------------------------------------------------------------------
  1  mail-client/squirrelmail      < 1.4.3a-r2            >= 1.4.3a-r2

Description
===========

SquirrelMail fails to properly sanitize certain strings when decoding
specially-crafted headers.

Impact
======

By enticing a user to read a specially-crafted e-mail, 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-1.4.3a-r2"

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