Severity:	high
Title:	Evolution: Integer overflow in camel-lock-helper
Date:	01/24/2005
Bugs:	#79183
ID:	200501-35

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	Architecture(s)
mail-client/evolution	<= 2.0.2	>= 2.0.2-r1	All supported architectures

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"
