Mozilla Firefox 3.0.10 allows remote attackers to cause a denial of service (infinite loop, application hang, and memory consumption) via a KEYGEN element in conjunction with (1) a META element specifying automatic page refresh or (2) a JavaScript onLoad event handler for a BODY element. NOTE: it was later reported that earlier versions are also affected.

Security readout for executives and security teams

This is an old browser denial-of-service issue in Mozilla Firefox 3.0.10, with later reporting that earlier versions were also affected. A malicious web page could make the browser hang and consume memory. The sources do not show data theft, code execution, or confirmed active exploitation. Exposure is mainly limited to organizations still running very old Firefox 3.x-era browsers, legacy kiosks, lab systems, or archived virtual desktops that can browse untrusted content. Treat as low urgency unless legacy Firefox is still operational. The business risk is availability disruption on obsolete browser endpoints, not confirmed compromise or data exposure from the supplied evidence. Mitigation focus: Identify and retire Firefox 3.0.10 or earlier installations.; Move affected users to a currently supported browser version.; Restrict legacy browsers from reaching untrusted websites..
