    Original advisory 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)

     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,

      tcpdump                         4.9.2-0ubuntu0.12.04.1
    
    In general, a standard system update will make all the necessary changes.
