Characteristics

This is a generic detection for a trojan that targets a heap buffer overflow in the Firefox  web browser version 1.5 via JavaScript garbage collection hazards . It may also affect Mozilla Suite, Mozilla SeaMonkey and Mozilla Thunderbird when JavaScript is enabled. Remote code execution is possible. Such exploit files could be executed with little user intervention - such as visiting a website that hosted malicious files, and the end result varies from memory corruption to the silent installation of any number of viruses, trojans and potentially unwanted programs.

This vulnerability is described in CVE-2006-0293 . Exploit code has been discovered in the wild . This vulnerability has been patched by the vendor, users of this application should update to version 1.5.0.1. More information on the vulnerability and the vendor's update can be found at:

All Information

Overview -

This is a trojan detection. Unlike viruses, trojans do not self-replicate. They are spread manually, often under the premise that they are beneficial or wanted. The most common installation methods involve system or security exploitation, and unsuspecting users manually executing unknown programs. Distribution channels include email, malicious or hacked web pages, Internet Relay Chat (IRC), peer-to-peer networks, etc.
