GLSA-200503-31 : Mozilla Firefox: Multiple vulnerabilities

This script is Copyright (C) 2005-2014 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-200503-31
(Mozilla Firefox: Multiple vulnerabilities)

The following vulnerabilities were found and fixed in Mozilla
Firefox:
Mark Dowd from ISS X-Force reported an
exploitable heap overrun in the GIF processing of obsolete Netscape
extension 2 (CAN-2005-0399)
Kohei Yoshino discovered that a
page bookmarked as a sidebar could bypass privileges control
(CAN-2005-0402)
Michael Krax reported a new way to bypass XUL
security restrictions through drag-and-drop of items like scrollbars
(CAN-2005-0401)

Impact :

The GIF heap overflow could be triggered by a malicious GIF
image that would end up executing arbitrary code with the rights of the
user running Firefox
By tricking the user into bookmarking a
malicious page as a Sidebar, a remote attacker could potentially
execute arbitrary code with the rights of the user running the
browser
By setting up a malicious website and convincing users
to obey very specific drag-and-drop instructions, attackers may
leverage drag-and-drop features to bypass XUL security restrictions,
which could be used as a stepping stone to exploit other
vulnerabilities

Workaround :

There is no known workaround at this time.
