In Wireshark 2.6.0 to 2.6.5, the 6LoWPAN dissector could crash. This was addressed in epan/dissectors/packet-6lowpan.c by avoiding use of a TVB before its creation.

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

  - In Wireshark 2.6.0 to 2.6.5, the 6LoWPAN dissector could crash. This was addressed in     epan/dissectors/packet-6lowpan.c by avoiding use of a TVB before its creation. (CVE-2019-5716)

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

Several issues in wireshark, a network traffic analyzer, have been found. Dissectors of

  - ISAKMP, a Internet Security Association and Key     Management Protocol

  - P_MUL, a reliable multicast transfer protocol

  - 6LoWPAN, IPv6 over Low power Wireless Personal Area     Network are affected.

CVE-2019-5719 Mateusz Jurczyk found that a missing encryption block in a packet could crash the ISAKMP dissector.

CVE-2019-5717 It was found that the P_MUL dissector could crash when a malformed packet contains an illegal Data PDU sequence number of 0.
Such a packet may not be analysed.

CVE-2019-5716 It was found that the 6LoWPAN dissector could crash when a malformed packet does not contain IPHC information though the header says it should.

For Debian 8 'Jessie', these problems have been fixed in version 1.12.1+g01b65bf-4+deb8u17.

We recommend that you upgrade your wireshark packages.

The version of Wireshark installed on the remote Windows host is prior to 2.6.6. It is, therefore, affected by multiple vulnerabilities as referenced in the wireshark-2.6.6 advisory.

  - In Wireshark 2.6.0 to 2.6.5 and 2.4.0 to 2.4.11, the ISAKMP dissector could crash. This was addressed in     epan/dissectors/packet-isakmp.c by properly handling the case of a missing decryption data block.
    (CVE-2019-5719)

  - In Wireshark 2.6.0 to 2.6.5, the 6LoWPAN dissector could crash. This was addressed in     epan/dissectors/packet-6lowpan.c by avoiding use of a TVB before its creation. (CVE-2019-5716)

  - In Wireshark 2.6.0 to 2.6.5 and 2.4.0 to 2.4.11, the P_MUL dissector could crash. This was addressed in     epan/dissectors/packet-p_mul.c by rejecting the invalid sequence number of zero. (CVE-2019-5717)

  - In Wireshark 2.6.0 to 2.6.5 and 2.4.0 to 2.4.11, the RTSE dissector and other ASN.1 dissectors could     crash. This was addressed in epan/charsets.c by adding a get_t61_string length check. (CVE-2019-5718)

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