Description Huzaifa S. Sidhpurwala 2016-12-14 06:52:07 UTC

A denial of service flaw was found in the way NSS handled handshake packets when SessionTicket extension was enabled on the TLS server side and ECDSA certificates were used. A remote attacker could use this flaw to crash TLS servers compiled against NSS.
