    Package        : nss
    CVE ID         : CVE-2015-2721 CVE-2015-2730
    
    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 (ECC) multiplication, allowing a remote attacker
        to potentially spoof ECDSA signatures.
    
    For the oldstable distribution (wheezy), these problems have been fixed
    in version 2:3.14.5-1+deb7u5.
    
    For the stable distribution (jessie), these problems have been fixed in
    version 2:3.17.2-1.1+deb8u1.
    
    For the testing distribution (stretch), these problems have been fixed
    in version 2:3.19.1-1.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 2:3.19.1-1.
    
    We recommend that you upgrade your nss packages.
