    Details:
    
    Wilfried Kirsch discovered a buffer overflow in the SLIP decoder
    in tcpdump. A remote attacker could use this to cause a denial
    of service (application crash) or possibly execute arbitrary
    code. (CVE-2017-11543)
    
    Bhargava Shastry discovered a buffer overflow in the bitfield converter
    utility function bittok2str_internal() in tcpdump. A remote attacker
    could use this to cause a denial of service (application crash)
    or possibly execute arbitrary code. (CVE-2017-13011)
    
    Otto Airamo and Antti Levomäki discovered logic errors in different
    protocol parsers in tcpdump that could lead to an infinite loop. A
    remote attacker could use these to cause a denial of service
    (application hang). CVE-2017-12989, CVE-2017-12990, CVE-2017-12995,
    CVE-2017-12997)
    
    Otto Airamo, Brian Carpenter, Yannick Formaggio, Kamil Frankowicz,
    Katie Holly, Kim Gwan Yeong, Antti Levomäki, Henri Salo, and Bhargava
    Shastry discovered out-of-bounds reads in muliptle protocol parsers
    in tcpdump.  A remote attacker could use these to cause a denial
    of service (application crash). (CVE-2017-11108, CVE-2017-11541,

    package versions:
    
    Ubuntu 17.04:
      tcpdump                         4.9.2-0ubuntu0.17.04.2
    
    Ubuntu 16.04 LTS:
      tcpdump                         4.9.2-0ubuntu0.16.04.1
    
    Ubuntu 14.04 LTS:
      tcpdump                         4.9.2-0ubuntu0.14.04.1
