The X.509 certificate validation functionality in Mozilla Firefox 4.0.x through 4.0.1 does not properly implement single-session security exceptions, which might make it easier for user-assisted remote attackers to spoof an SSL server via an untrusted certificate that triggers potentially unwanted local caching of documents from that server.

Security readout for executives and security teams

CVE-2011-0082 is an old Firefox certificate-validation issue. In Firefox 4.0.x through 4.0.1, temporary certificate exceptions could behave incorrectly, potentially making SSL server spoofing easier after user interaction with an untrusted certificate. Exposure is most plausible on endpoints still running Firefox 4.0.x through 4.0.1 or distribution packages derived from those versions. Modern supported Firefox versions are not identified as affected in the provided sources. Treat as legacy exposure cleanup unless affected Firefox versions remain in use. Prioritize replacement in regulated, kiosk, or unmanaged endpoint environments where users may encounter certificate warnings. Mitigation focus: Inventory and retire Firefox 4.0.x through 4.0.1 installations.; Check Mozilla, Debian, and Red Hat guidance for applicable fixed packages.; Do not allow users to bypass untrusted certificate warnings on affected browsers..
