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"
