    Several vulnerabilities have been discovered in the Linux kernel that
    may lead to a privilege escalation or denial-of-service.
    
    CVE-2013-4312
    
        Tetsuo Handa discovered that it is possible for a process to open
        far more files than the process' limit leading to denial-of-service
        conditions.
    
    CVE-2015-7566
    
        Ralf Spenneberg of OpenSource Security reported that the visor
        driver crashes when a specially crafted USB device without bulk-out
        endpoint is detected.
    
    CVE-2015-8767
    
        An SCTP denial-of-service was discovered which can be triggered by a
        local attacker during a heartbeat timeout event after the 4-way
        handshake.
    
    CVE-2016-0723
    
        A use-after-free vulnerability was discovered in the TIOCGETD ioctl.
        A local attacker could use this flaw for denial-of-service.
    
    CVE-2016-0728
    
        The Perception Point research team discovered a use-after-free
        vulnerability in the keyring facility, possibly leading to local
        privilege escalation.
    
    For the stable distribution (jessie), these problems have been fixed in
    version 3.16.7-ckt20-1+deb8u3.
    
    We recommend that you upgrade your linux packages.
