The layout engine in Mozilla Firefox before 4.0, Thunderbird before 3.3, and SeaMonkey before 2.1 executes different code for visited and unvisited links during the processing of Cascading Style Sheets (CSS) token sequences, which makes it easier for remote attackers to obtain sensitive information about visited web pages via a timing attack.

Security readout for executives and security teams

This CVE is an old Mozilla privacy flaw where a malicious website could infer whether a user had visited certain pages. It did not describe system takeover, but it could reveal sensitive browsing history. The exposed products are Firefox before 4.0, Thunderbird before 3.3, and SeaMonkey before 2.1. Exposure is most likely limited to legacy systems still running the named Mozilla versions. Modern environments should mainly validate that unsupported Firefox, Thunderbird, or SeaMonkey installations are not present. Treat this as a legacy hygiene and privacy issue, not an emergency patch event. Prioritize remediation if old Mozilla clients remain on sensitive workstations or regulated environments. Mitigation focus: Upgrade Firefox to 4.0 or later where applicable.; Upgrade Thunderbird to 3.3 or later where applicable.; Upgrade SeaMonkey to 2.1 or later where applicable..
