GLSA-200501-03 : Mozilla, Firefox, Thunderbird: Various 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-200501-03
(Mozilla, Firefox, Thunderbird: Various vulnerabilities)

Maurycy Prodeus from isec.pl found a potentially exploitable buffer
overflow in the handling of NNTP URLs. Furthermore, Martin (from
ptraced.net) discovered that temporary files in recent versions of
Mozilla-based products were sometimes stored world-readable with
predictable names. The Mozilla Team also fixed a way of spoofing
filenames in Firefox's 'What should Firefox do with this file' dialog
boxes and a potential information leak about the existence of local
filenames.

Impact :

A remote attacker could craft a malicious NNTP link and entice a user
to click it, potentially resulting in the execution of arbitrary code
with the rights of the user running the browser. A local attacker could
leverage the temporary file vulnerability to read the contents of
another user's attachments or downloads. A remote attacker could also
design a malicious web page that would allow to spoof filenames if the
user uses the 'Open with...' function in Firefox, or retrieve
information on the presence of specific files in the local filesystem.

Workaround :

There is no known workaround at this time.
