The version of Wireshark installed on the remote macOS / Mac OS X host is prior to 2.4.15. It is, therefore, affected by a flaw in the dissection engine which could crash. It may be possible to make Wireshark crash by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file.

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

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4133-1 advisory.

    It was discovered that Wireshark improperly handled certain input. A remote or local attacker could cause     Wireshark to crash by injecting malformed packets onto the wire or convincing someone to read a malformed     packet trace file.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

In Wireshark 3.0.0 to 3.0.1, 2.6.0 to 2.6.8, and 2.4.0 to 2.4.14, the dissection engine could crash. This was addressed in epan/packet.c by restricting the number of layers and consequently limiting recursion.
(CVE-2019-12295)

Impact

An attacker can leverage this issue to stop the affected application and deny service to legitimate users.

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

  - In Wireshark 3.0.0 to 3.0.1, 2.6.0 to 2.6.8, and 2.4.0 to 2.4.14, the dissection engine could crash. This     was addressed in epan/packet.c by restricting the number of layers and consequently limiting recursion.
    (CVE-2019-12295)

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

Several vulnerabilities were fixed in the Wireshark network protocol analyzer.
