Improper Implementation of Single-Session Security Exceptions in Mozilla Firefox 4.0.x through 4.0.1

CVE-2011-0082

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.
