Mozilla Products: Multiple vulnerabilities

Background

Mozilla Firefox is an open-source web browser and Mozilla Thunderbird an open-source email client, both from the Mozilla Project. The SeaMonkey project is a community effort to deliver production-quality releases of code derived from the application formerly known as the ‘Mozilla Application Suite’. XULRunner is a Mozilla runtime package that can be used to bootstrap XUL+XPCOM applications such as Firefox and Thunderbird. NSS is Mozilla’s Network Security Services library that implements PKI support. IceCat is the GNU version of Firefox.

Description

Multiple vulnerabilities have been discovered in Mozilla Firefox, Thunderbird, SeaMonkey, NSS, GNU IceCat, and XULRunner. Please review the CVE identifiers referenced below for details.

Impact

A remote attacker could entice a user to view a specially crafted web page or email, possibly resulting in execution of arbitrary code or a Denial of Service condition. Furthermore, a remote attacker may be able to perform Man-in-the-Middle attacks, obtain sensitive information, bypass restrictions and protection mechanisms, force file downloads, conduct XML injection attacks, conduct XSS attacks, bypass the Same Origin Policy, spoof URL’s for phishing attacks, trigger a vertical scroll, spoof the location bar, spoof an SSL indicator, modify the browser’s font, conduct clickjacking attacks, or have other unspecified impact.

A local attacker could gain escalated privileges, obtain sensitive information, or replace an arbitrary downloaded file.

Workaround

There is no known workaround at this time.
