Firefox ESR 31.x < 31.1.1 NSS Signature Verification Vulnerability (Mac OS X)

High Nessus Plugin ID 77900


The remote Mac OS X host contains a web browser that is affected by a signature forgery vulnerability.


The version of Firefox ESR 31.x installed on the remote host is prior to 31.1.1. It is, therefore, affected by a flaw in the Network Security Services (NSS) library, which is due to lenient parsing of ASN.1 values involved in a signature and can lead to the forgery of RSA signatures, such as SSL certificates.


Upgrade to Firefox ESR 31.1.1 or later.
