Synopsis
========

An overflow in the camel-lock-helper application can be exploited by an
attacker to execute arbitrary code with elevated privileges.

Background
==========

Evolution is a GNOME groupware application similar to Microsoft
Outlook.

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

    -------------------------------------------------------------------
     Package                /  Vulnerable  /                Unaffected
    -------------------------------------------------------------------
  1  mail-client/evolution      <= 2.0.2                   >= 2.0.2-r1

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

Max Vozeler discovered an integer overflow in the camel-lock-helper
application, which is installed as setgid mail by default.

Impact
======

A local attacker could exploit this vulnerability to execute malicious
code with the privileges of the 'mail' group. A remote attacker could
also setup a malicious POP server to execute arbitrary code when an
Evolution user connects to it.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Evolution users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose
    # ">=mail-client/evolution-2.0.2-r1"
