Description

Mozilla Firefox, Thunderbird and SeaMonkey contain a flaw that may allow an attacker to gain access to unauthorized privileges. The issue is triggered when an attacker uses malicious JavaScript, hosted on a crafted website, to call code within a signed JAR file that was cached from a trusted site. The malicious JavaScript then inherits the privileges of the JAR file and an elevation of privileges occurs, allowing a remote attacker to inherit the trust of the site hosting the JAR file and gain privileges granted to it by the user.
