The version of Thunderbird 24.x installed on the remote host is prior to 24.8.1. 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.
