Antoine Delignat-Lavaud, security researcher at Inria Paris in team
Prosecco, reported an issue in Network Security Services (NSS) libraries
affecting all versions. He discovered that NSS is vulnerable to a
variant of a signature forgery attack previously published by Daniel
Bleichenbacher. This is due to lenient parsing of ASN.1 values involved
in a signature and could lead to the forging of RSA certificates.
The Advanced Threat Research team at Intel Security also independently
discovered and reported this issue.
