The js_InitRandom function in the JavaScript implementation in Mozilla Firefox 3.5.10 through 3.5.11, 3.6.4 through 3.6.8, and 4.0 Beta1 uses a context pointer in conjunction with its successor pointer for seeding of a random number generator, which makes it easier for remote attackers to guess the seed value via a brute-force attack, a different vulnerability than CVE-2010-3171.

Security readout for executives and security teams

This is an old Firefox browser weakness where JavaScript random numbers could be easier to predict. A malicious website could potentially use that predictability for cross-domain information leakage. The listed affected versions are Firefox 3.5.10-3.5.11, 3.6.4-3.6.8, and 4.0 Beta1. Exposure is mainly legacy desktops, kiosks, embedded systems, VDI images, or test environments still running the affected Firefox versions. Current supported Firefox deployments are not identified as affected in the source bundle. Treat this as a legacy exposure cleanup item unless affected Firefox versions are still present. Business urgency rises if old browsers access sensitive internal apps or untrusted internet content. Mitigation focus: Remove or upgrade affected Firefox versions to supported releases.; Check Mozilla guidance before selecting any specific fixed version.; Block legacy Firefox from internet browsing until remediated..
