0-Day Exploit for Critical Firefox Vulnerability
The release of proof-of-concept exploit code for an unresolved critical bug that allows for remote arbitrary code execution on the latest stable version of Mozilla Firefox has put developers on alert. A fix will be included in the 3.0.8 version of the browser, which is scheduled for release in a few days.
The vulnerability is described on SecurityFocus as a “Boundary Condition Error” and allows an attacker to execute potentially malicious code by calling a malformed XML file from a Web page. Parsing a specially crafted “root” XML tag in an XSL file results in a memory-corruption error.
These drive-by types of attacks have become the weapon of choice for many of today’s malware distributors.

These exploits target vulnerabilities in popular software such as Adobe Reader, Flash Player, or the browsers themselves. Read More»
