"Several vulnerabilities have been discovered in the Linux kernel that
may lead to a denial of service, information leaks or privilege
escalation :

  - CVE-2014-0196
    Jiri Slaby discovered a race condition in the pty layer,
    which could lead to denial of service or privilege
    escalation.

  - CVE-2014-1737 / CVE-2014-1738
    Matthew Daley discovered that missing input sanitising
    in the FDRAWCMD ioctl and an information leak could
    result in privilege escalation.

  - CVE-2014-2851
    Incorrect reference counting in the ping_init_sock()
    function allows denial of service or privilege
    escalation.

  - CVE-2014-3122
    Incorrect locking of memory can result in local denial
    of service.");
