"The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in
the USN-5769-1 advisory.

  - protobuf allows remote authenticated attackers to cause a heap-based buffer overflow. (CVE-2015-5237)

  - A parsing vulnerability for the MessageSet type in the ProtocolBuffers versions prior to and including
    3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 3.21.5 for protobuf-cpp, and versions prior to and including
    3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 4.21.5 for protobuf-python can lead to out of memory failures.
    A specially crafted message with multiple key-value per elements creates parsing issues, and can lead to a
    Denial of Service against services receiving unsanitized input. We recommend upgrading to versions 3.18.3,
    3.19.5, 3.20.2, 3.21.6 for protobuf-cpp and 3.18.3, 3.19.5, 3.20.2, 4.21.6 for protobuf-python. Versions
    for 3.16 and 3.17 are no longer updated. (CVE-2022-1941)

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