    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.
