Background ========== libqb is a library with the primary purpose of providing high-performance, reusable features for client-server architecture, such as logging, tracing, inter-process communication (IPC), and polling. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-cluster/libqb < 1.0.5 >= 1.0.5 Description =========== It was discovered that libqb used predictable filenames (under /dev/shm and /tmp) without O_EXCL. Impact ====== A local attacker could perform symlink attacks to overwrite arbitrary files with the privileges of the user running the application linked against libqb. Workaround ========== There is no known workaround at this time. Resolution ========== All libqb users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-cluster/libqb-1.0.5" References ========== [ 1 ] CVE-2019-12779 https://nvd.nist.gov/vuln/detail/CVE-2019-12779 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/202107-03 Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
