Firefox < 32.0.3 NSS Signature Verification Vulnerability (Mac OS X)

This script is Copyright (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

The version of Firefox installed on the remote host is prior to
32.0.3. 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.
