Red Hat Security Advisory 2023-5597-01 - The libqb packages provide a library with the primary purpose of providing high performance client/server reusable features, such as high performance logging, tracing, inter-process communication, and polling. Issues addressed include a buffer overflow vulnerability.
log_blackbox.c in libqb before 2.0.8 allows a buffer overflow via long log messages because the header size is not considered.
