Last modified Jun 17, 2026

CVE-2014-8642 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.57% chance of exploitation in the next 30 days.
