Security Fix(es) :

  - A use-after-free flaw was found in the way NSS handled
    DHE (Diffie- Hellman key exchange) and ECDHE (Elliptic
    Curve Diffie-Hellman key exchange) handshake messages. A
    remote attacker could send a specially crafted handshake
    message that, when parsed by an application linked
    against NSS, would cause that application to crash or,
    under certain special conditions, execute arbitrary code
    using the permissions of the user running the
    application. (CVE-2016-1978)

  - A use-after-free flaw was found in the way NSS processed
    certain DER (Distinguished Encoding Rules) encoded
    cryptographic keys. An attacker could use this flaw to
    create a specially crafted DER encoded certificate
    which, when parsed by an application compiled against
    the NSS library, could cause that application to crash,
    or execute arbitrary code using the permissions of the
    user running the application. (CVE-2016-1979)"
