Mandriva Linux Security Advisory 2014-252 - In the QuickDER decoder in NSS before 3.17.3, ASN.1 DER decoding of lengths is too permissive, allowing undetected smuggling of arbitrary data. This update adds support for the TLS Fallback Signaling Cipher Suite Value in NSS, which can be used to prevent protocol downgrade attacks against applications which re-connect using a lower SSL/TLS protocol version when the initial connection indicating the highest supported protocol version fails. This can prevent a forceful downgrade of the communication to SSL 3.0, mitigating also known as POODLE. SSL 3.0 support has also been disabled by default in this Firefox and Thunderbird update, further mitigating POODLE.
