A new version of the popular web browser Firefox (3.0.9) addresses multiple vulnerabilities, such as POST data being sent to the wrong site when saving web pages, allowing malicious search plug-ins to inject code into arbitrary sites, and cross-site scripting hazards when using third-party stylesheets. Exploitation of these vulnerabilities could enable an attacker to execute arbitrary code, leverage additional attacks, or obtain sensitive information, according to US-CERT. — CAM
