It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2023-294 advisory.

  • log_blackbox.c in libqb before 2.0.8 allows a buffer overflow via long log messages because the header size is not considered. (CVE-2023-39976)

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