Description

The version of Thunderbird installed on the remote host is prior to 31.1.2. 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.
