Mozilla developer John G. Myers reported a weakness in the trust model used by Mozilla regarding alternate names on self-signed certificates (and those with mismatched names) that if accepted could be used to spoof a secure connection to any other site. This problem was independently reported by Frank Benkstein and Nils Toedtmann.
