| CVE-2021-35000 | 1 Openbsd | 1 Openbsd | 2025-08-14 | N/A |
| OpenBSD Kernel Multicast Routing Uninitialized Memory Information Disclosure Vulnerability. This vulnerability allows local attackers to disclose sensitive information on affected installations of OpenBSD Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the implementation of multicast routing. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute arbitrary code in the context of the kernel. . Was ZDI-CAN-16112. | ||||
| CVE-2020-15778 | 4 Broadcom, Netapp, Openbsd and 1 more | 11 Fabric Operating System, A700s, A700s Firmware and 8 more | 2025-07-28 | 7.4 High |
| scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that could "stand a great chance of breaking existing workflows." | ||||
| CVE-2024-29937 | 2 Freebsd, Openbsd | 2 Freebsd, Openbsd | 2025-06-17 | 9.8 Critical |
| NFS in a BSD derived codebase, as used in OpenBSD through 7.4 and FreeBSD through 14.0-RELEASE, allows remote attackers to execute arbitrary code via a bug that is unrelated to memory corruption. | ||||
| CVE-2025-32728 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2025-05-22 | 4.3 Medium |
| In sshd in OpenSSH before 10.0, the DisableForwarding directive does not adhere to the documentation stating that it disables X11 and agent forwarding. | ||||
| CVE-2019-16905 | 3 Netapp, Openbsd, Siemens | 7 Cloud Backup, Steelstore Cloud Integrated Storage, Openssh and 4 more | 2025-04-23 | 7.8 High |
| OpenSSH 7.7 through 7.9 and 8.x before 8.1, when compiled with an experimental key type, has a pre-authentication integer overflow if a client or server is configured to use a crafted XMSS key. This leads to memory corruption and local code execution because of an error in the XMSS key parsing algorithm. NOTE: the XMSS implementation is considered experimental in all released OpenSSH versions, and there is no supported way to enable it when building portable OpenSSH. | ||||
| CVE-2016-6244 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| The sys_thrsigdivert function in kern/kern_sig.c in the OpenBSD kernel 5.9 allows remote attackers to cause a denial of service (panic) via a negative "ts.tv_sec" value. | ||||
| CVE-2016-6239 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| The mmap extension __MAP_NOFAULT in OpenBSD 5.8 and 5.9 allows attackers to cause a denial of service (kernel panic and crash) via a large size value. | ||||
| CVE-2016-6245 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| OpenBSD 5.8 and 5.9 allows local users to cause a denial of service (kernel panic) via a large size in a getdents system call. | ||||
| CVE-2016-6240 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| Integer truncation error in the amap_alloc function in OpenBSD 5.8 and 5.9 allows local users to execute arbitrary code with kernel privileges via a large size value. | ||||
| CVE-2016-6243 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| thrsleep in kern/kern_synch.c in OpenBSD 5.8 and 5.9 allows local users to cause a denial of service (kernel panic) via a crafted value in the tsp parameter of the __thrsleep system call. | ||||
| CVE-2017-15906 | 5 Debian, Netapp, Openbsd and 2 more | 23 Debian Linux, Active Iq Unified Manager, Cloud Backup and 20 more | 2025-04-20 | 5.3 Medium |
| The process_open function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write operations in readonly mode, which allows attackers to create zero-length files. | ||||
| CVE-2017-1000372 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| 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. This affects OpenBSD 6.1 and possibly earlier versions. | ||||
| CVE-2016-1908 | 4 Debian, Openbsd, Oracle and 1 more | 10 Debian Linux, Openssh, Linux and 7 more | 2025-04-20 | 9.8 Critical |
| The client in OpenSSH before 7.2 mishandles failed cookie generation for untrusted X11 forwarding and relies on the local X11 server for access-control decisions, which allows remote X11 clients to trigger a fallback and obtain trusted X11 forwarding privileges by leveraging configuration issues on this X11 server, as demonstrated by lack of the SECURITY extension on this X11 server. | ||||
| CVE-2016-6522 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| 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. | ||||
| CVE-2017-8301 | 1 Openbsd | 1 Libressl | 2025-04-20 | N/A |
| LibreSSL 2.5.1 to 2.5.3 lacks TLS certificate verification if SSL_get_verify_result is relied upon for a later check of a verification result, in a use case where a user-provided verification callback returns 1, as demonstrated by acceptance of invalid certificates by nginx. | ||||
| CVE-2017-1000373 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| 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. | ||||
| CVE-2016-6350 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |

| CVE-2016-6246 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| OpenBSD 5.8 and 5.9 allows certain local users with kern.usermount privileges to cause a denial of service (kernel panic) by mounting a tmpfs with a VNOVAL in the (1) username, (2) groupname, or (3) device name of the root node. | ||||
| CVE-2016-6241 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| Integer overflow in the amap_alloc1 function in OpenBSD 5.8 and 5.9 allows local users to execute arbitrary code with kernel privileges via a large size value. | ||||
| CVE-2016-6247 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| 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. | ||||
