GLSA-200408-02 : Courier: Cross-site scripting vulnerability in SqWebMail

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200408-02
(Courier: Cross-site scripting vulnerability in SqWebMail)

Luca Legato found that SqWebMail is vulnerable to a cross-site scripting
(XSS) attack. An XSS attack allows an attacker to insert malicious code
into a web-based application. SqWebMail doesn't filter appropriately data
coming from message headers before displaying them.

Impact :

By sending a carefully crafted message, an attacker can inject and execute
script code in the victim's browser window. This allows to modify the
behaviour of the SqWebMail application, and/or leak session information
such as cookies to the attacker.

Workaround :

There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version of Courier.
