Libqb Security Vulnerabilities

CVE-2019-12779

libqb before 1.0.5 allows local users to overwrite arbitrary files via a symlink attack, because it uses predictable filenames (under /dev/shm and /tmp) without O_EXCL.

CVE-2023-39976

log_blackbox.c in libqb before 2.0.8 allows a buffer overflow via long log messages because the header size is not considered.
