Mozilla Firefox before 35.0 and SeaMonkey before 2.32 do not consider the id-pkix-ocsp-nocheck extension in deciding whether to trust an OCSP responder, which makes it easier for remote attackers to obtain sensitive information by sniffing the network during a session in which there was an incorrect decision to accept a compromised and revoked certificate.

Security readout for executives and security teams

This CVE concerns old Mozilla browsers making a wrong trust decision around certificate revocation checks. In a specific network-sniffing scenario involving a compromised and revoked certificate, attackers could more easily read sensitive session information. Exposure is most likely limited to legacy Firefox or SeaMonkey installations, including older Linux distribution packages or bundled browser components documented by vendor advisories. Treat this as a legacy exposure cleanup item, not an emergency, unless old Mozilla browsers remain in regulated, high-sensitivity, or interception-heavy environments. Mitigation focus: Upgrade Firefox to 35.0 or later where Firefox is still deployed.; Upgrade SeaMonkey to 2.32 or later where SeaMonkey is still deployed.; Apply relevant distribution or vendor security updates for packaged browser builds..
