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 2.6.x prior to 2.6.6. It is, therefore, affected by multiple denial of service vulnerabilities in the following protocol dissectors:

  - 6LoWPAN

  - P_MUL

  - RTSE

  - ISAKMP

An attacker could cause Wireshark to crash by injecting a malformed packet onto the wire, or by convincing a user to read a malformed packet trace file.

The version of Wireshark installed on the remote macOS / Mac OS X host is 2.6.x prior to 2.6.6. It is, therefore, affected by multiple denial of service vulnerabilities in the following protocol dissectors:

  - 6LoWPAN

  - P_MUL

  - RTSE

  - ISAKMP

An attacker could cause Wireshark to crash by injecting a malformed packet onto the wire, or by convincing a user to read a malformed packet trace file.
