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 •

28 Jul 2020 — iked in OpenIKED, as used in OpenBSD through 6.7, allows authentication bypass because ca.c has the wrong logic for checking whether a public key matches. iked en OpenIKED, como es usado en OpenBSD versiones hasta 6.7, permite omitir una autenticación porque el archivo ca.c presenta una lógica equivocada para comprobar si una clave pública coincide • https://ftp.openbsd.org/pub/OpenBSD/patches/6.7/common/014_iked.patch.sig • CWE-287: Improper Authentication •
CVSS: 7.8EPSS: 10%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 •

26 Aug 2019 — OpenBSD kernel version <= 6.5 can be forced to create long chains of TCP SACK holes that causes very expensive calls to tcp_sack_option() for every incoming SACK packet which can lead to a denial of service.

https://notcve.org/view.php?id=CVE-2017-1000373
19 Jun 2017 — The OpenBSD qsort() function is recursive, and not randomized, an attacker can construct a pathological input array of N elements that causes qsort() to deterministically recurse N/4 times. This allows attackers to consume arbitrary amounts of stack memory and manipulate stack memory to assist in arbitrary code execution attacks. This affects OpenBSD 6.1 and possibly earlier versions. La función qsort() de OpenBSD es recursiva y no aleatorizada, por lo que un atacante puede construir un array de entrada pat... • https://packetstorm.news/files/id/143206 • CWE-400: Uncontrolled Resource Consumption •
