epan/dissectors/packet-wbxml.c in the WBXML dissector in Wireshark 2.x before 2.0.5 does not restrict the recursion depth, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - epan/dissectors/packet-wbxml.c in the WBXML dissector in Wireshark 2.x before 2.0.5 does not restrict the     recursion depth, which allows remote attackers to cause a denial of service (application crash) via a     crafted packet. (CVE-2016-6513)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of Wireshark installed on the remote Windows host is 2.0.x prior to 2.0.5. It is, therefore, affected by multiple denial of service vulnerabilities :

  - A denial of service vulnerability exists in the CORBA     IDL dissector due to improper handling of packets. An     unauthenticated, remote attacker can exploit this, via a     specially crafted packet or packet trace file, to cause     an application crash. Note that this vulnerability only     affects 64-bit versions of Windows. (CVE-2016-6503)

  - A denial of service vulnerability exists due to a     divide-by-zero flaw in the dissect_pbb_tlvblock()     function in packet-packetbb.c. An unauthenticated,     remote attacker can exploit this, via a specially     crafted packet or packet trace file, to cause an     application crash. (CVE-2016-6505)

  - A flaw exists in the add_headers() function in     packet_wsp.c that is triggered when an offset of zero is     returned by the wkh_content_disposition() function. An     unauthenticated, remote attacker can exploit this, via a     specially crafted packet or packet trace file, to cause     an infinite loop, resulting in a denial of service     condition. (CVE-2016-6506)

  - A denial of service vulnerability exists due to an     incorrect integer data type used in the rlc_decode_li()     function in packet-rlc.c. An unauthenticated, remote     attacker can exploit this, via a specially crafted     packet or packet trace file, to cause a long loop and     excessive CPU resource consumption, resulting in a     denial of service condition. (CVE-2016-6508)

  - A denial of service vulnerability exists in the     dissect_ldss_transfer() function in packet-ldss.c that     is triggered when recreating a conversation that already     exists. An unauthenticated, remote attacker can exploit     this, via a specially crafted packet or packet trace     file, to cause an application crash. (CVE-2016-6509)

  - An overflow condition exists in the rlc_decode_li()     function in packet-rlc.c due to improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit this, via a specially crafted packet or     packet trace file, to cause a stack-based buffer     overflow, resulting in a denial of service condition.
    (CVE-2016-6510)

  - A denial of service vulnerability exists in the     proto_tree_add_text_valist_internal() function in     proto.c due to improper handling of packets. An     unauthenticated, remote attacker can exploit this, via a     specially crafted packet or packet trace file, to cause     a long loop and excessive CPU resource consumption.
    (CVE-2016-6511)

  - Multiple flaws exist in the MMSE, WAP, WBXML, and WSP     dissectors due to improper handling of packets. An     unauthenticated, remote attacker can exploit these     issues, via a specially crafted packet or packet trace     file, to cause an infinite loop, resulting in a denial     of service condition. (CVE-2016-6512)

  - A denial of service vulnerability exists in the     parse_wbxml_tag_defined() function in packet-wbxml.c due     to improper handling of packets. An unauthenticated,     remote attacker can exploit this, via a specially     crafted packet or packet trace file, to cause an     application crash. (CVE-2016-6513)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
