Description

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.

Affected products

Mozilla Firefox: 4.0, 4.0-beta1, 4.0-beta10, 4.0-beta11, 4.0-beta12, 4.0-beta2 (+8)
