| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-04-15 | CVE-2021-46880 | Improper Certificate Validation vulnerability in Openbsd 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. | 9.8 |
| 2023-04-12 | CVE-2022-48437 | Improper Certificate Validation vulnerability in Openbsd An issue was discovered in x509/x509_verify.c in LibreSSL before 3.6.1, and in OpenBSD before 7.2 errata 001. | 5.3 |
| 2020-07-28 | CVE-2020-16088 | Improper Authentication vulnerability in Openbsd 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. | 9.8 |
| 2019-12-12 | CVE-2019-19726 | Improper Privilege Management vulnerability in Openbsd 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. | 7.8 |
| 2019-08-26 | CVE-2019-8460 | Unspecified vulnerability in Openbsd 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. | 7.5 |
| 2017-06-19 | CVE-2017-1000373 | Resource Exhaustion vulnerability in Openbsd 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. | 6.5 |
| 2017-06-19 | CVE-2017-1000372 | Unspecified vulnerability in Openbsd A flaw exists in OpenBSD's implementation of the stack guard page that allows attackers to bypass it resulting in arbitrary code execution using setuid binaries such as /usr/bin/at. | 9.8 |
| 2017-03-07 | CVE-2016-6522 | Integer Overflow or Wraparound vulnerability in Openbsd 5.9 Integer overflow in the uvm_map_isavail function in uvm/uvm_map.c in OpenBSD 5.9 allows local users to cause a denial of service (kernel panic) via a crafted mmap call, which triggers the new mapping to overlap with an existing mapping. | 5.5 |
| 2017-03-07 | CVE-2016-6350 | NULL Pointer Dereference vulnerability in Openbsd 5.8/5.9 OpenBSD 5.8 and 5.9 allows local users to cause a denial of service (NULL pointer dereference and panic) via a sysctl call with a path starting with 10,9. | 5.5 |
| 2017-03-07 | CVE-2016-6247 | Improper Input Validation vulnerability in Openbsd 5.8/5.9 OpenBSD 5.8 and 5.9 allows certain local users to cause a denial of service (kernel panic) by unmounting a filesystem with an open vnode on the mnt_vnodelist. | 5.5 |
