The Cascading Style Sheets (CSS) implementation in Mozilla Firefox before 4.0, Thunderbird before 3.3, and SeaMonkey before 2.1 does not properly handle the :visited pseudo-class, which allows remote attackers to obtain sensitive information about visited web pages via a crafted HTML document, a related issue to CVE-2010-2264.

Security readout for executives and security teams

This is an old Mozilla privacy flaw where a malicious web page could infer some sites a user had visited by abusing CSS handling of visited links. It affects legacy Firefox, Thunderbird, and SeaMonkey versions named in the CVE. The source bundle does not show active exploitation or a CVSS score. Exposure is most likely where obsolete Mozilla browser or mail clients can render untrusted HTML. Modern supported deployments are unlikely to be affected, but legacy systems, kiosks, archived builds, or embedded browser components should be checked. Treat this as a legacy exposure cleanup item unless affected clients still exist in production. Business urgency rises if obsolete Mozilla software is used on sensitive workstations or in environments where users open untrusted web or email content. Mitigation focus: Upgrade Firefox to 4.0 or later, Thunderbird to 3.3 or later, and SeaMonkey to 2.1 or later.; Prefer currently supported vendor versions, not merely historical minimum fixed releases.; Remove unsupported Mozilla clients from managed endpoints and gold images..
