29 Aug 2023 — In OpenBGPD before 8.1, incorrect handling of BGP update data (length of path attributes) set by a potentially distant remote actor may cause the system to incorrectly reset a session. This is fixed in OpenBSD 7.3 errata 006. • https://blog.benjojo.co.uk/post/bgp-path-attributes-grave-error-handling • CWE-754: Improper Check for Unusual or Exceptional Conditions •

14 Apr 2023 — x509/x509_verify.c in LibreSSL before 3.4.2, and OpenBSD before 7.0 errata 006, allows authentication bypass because an error for an unverified certificate chain is sometimes discarded. • https://ftp.openbsd.org/pub/OpenBSD/LibreSSL/libressl-3.4.2-relnotes.txt • CWE-295: Improper Certificate Validation •

12 Apr 2023 — An issue was discovered in x509/x509_verify.c in LibreSSL before 3.6.1, and in OpenBSD before 7.2 errata 001. x509_verify_ctx_add_chain does not store errors that occur during leaf certificate verification, and therefore an incorrect error is returned. This behavior occurs when there is an installed verification callback that instructs the verifier to continue upon detecting an invalid certificate. • https://ftp.openbsd.org/pub/OpenBSD/LibreSSL/libressl-3.6.1-relnotes.txt • CWE-295: Improper Certificate Validation •

CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 8CVE-2019-19726 – OpenBSD 6.x - Dynamic Loader Privilege Escalation
https://notcve.org/view.php?id=CVE-2019-19726
12 Dec 2019 — OpenBSD through 6.6 allows local users to escalate to root because a check for LD_LIBRARY_PATH in setuid programs can be defeated by setting a very small RLIMIT_DATA resource limit. When executing chpass or passwd (which are setuid root), _dl_setup_env in ld.so tries to strip LD_LIBRARY_PATH from the environment, but fails when it cannot allocate memory. Thus, the attacker is able to execute their own library code as root. OpenBSD versiones hasta 6.6, permite a usuarios locales escalar a root porque una com... • https://packetstorm.news/files/id/174986 • CWE-269: Improper Privilege Management •
