  - CVE-2016-7178: epan/dissectors/packet-umts_fp.c in the     UMTS FP dissector in Wireshark did not ensure that     memory is allocated for certain data structures, which     allowed remote attackers to cause a denial of service     (invalid write access and application crash) via a     crafted packet (bsc#998964)

  - CVE-2016-7177: epan/dissectors/packet-catapult-dct2000.c     in the Catapult DCT2000 dissector in Wireshark did not     restrict the number of channels, which allowed remote     attackers to cause a denial of service (buffer over-read     and application crash) via a crafted packet (bsc#998763)

  - CVE-2016-7176: epan/dissectors/packet-h225.c in the     H.225 dissector in Wireshark called snprintf with one of     its input buffers as the output buffer, which allowed     remote attackers to cause a denial of service (copy     overlap and application crash) via a crafted packet     (bsc#998762)
