Several vulnerabilities have been discovered in nss, the Mozilla Network Security Service library. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2015-2721 Karthikeyan Bhargavan discovered that NSS incorrectly handles state transitions for the TLS state machine. A man-in-the-middle attacker could exploit this flaw to skip the ServerKeyExchange message and remove the forward-secrecy property. CVE-2015-2730 Watson Ladd discovered that NSS does not properly perform Elliptical Curve Cryptography multiplication, allowing a remote attacker to potentially spoof ECDSA signatures.
