"The remote SUSE Linux SUSE15 host has packages installed that are affected by a vulnerability as referenced in the
openSUSE-SU-2022:0823-1 advisory.

  - Nullptr dereference when a null char is present in a proto symbol. The symbol is parsed incorrectly,
    leading to an unchecked call into the proto file's name during generation of the resulting error message.
    Since the symbol is incorrectly parsed, the file is nullptr. We recommend upgrading to version 3.15.0 or
    greater. (CVE-2021-22570)

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