Synopsis
An application installed on the remote macOS / Mac OS X host is affected by multiple vulnerabilities.Description
The version of Wireshark installed on the remote macOS / Mac OS X 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.
