"details": "Karthikeyan Bhargavan discovered that NSS incorrectly handled state\ntransitions for the TLS state machine. If a remote attacker were able to\nperform a machine-in-the-middle attack, this flaw could be exploited to skip\nthe ServerKeyExchange message and remove the forward-secrecy property.\n(CVE-2015-2721)\n\nWatson Ladd discovered that NSS incorrectly handled Elliptical Curve\nCryptography (ECC) multiplication. A remote attacker could possibly use\nthis issue to spoof ECDSA signatures. (CVE-2015-2730)\n\nAs a security improvement, this update modifies NSS behaviour to reject DH\nkey sizes below 768 bits, preventing a possible downgrade attack.\n\nThis update also refreshes the NSS package to version 3.19.2 which includes\nthe latest CA certificate bundle.\n",
