| CVE-1999-0304 | 4 Bsdi, Freebsd, Netbsd and 1 more | 4 Bsd Os, Freebsd, Netbsd and 1 more | 2025-04-03 | N/A |
| mmap function in BSD allows local attackers in the kmem group to modify memory through devices. | ||||
| CVE-1999-0305 | 3 Bsdi, Freebsd, Openbsd | 3 Bsd Os, Freebsd, Openbsd | 2025-04-03 | N/A |
| The system configuration control (sysctl) facility in BSD based operating systems OpenBSD 2.2 and earlier, and FreeBSD 2.2.5 and earlier, does not properly restrict source routed packets even when the (1) dosourceroute or (2) forwarding variables are set, which allows remote attackers to spoof TCP connections. | ||||
| CVE-1999-0482 | 1 Openbsd | 1 Openbsd | 2025-04-03 | N/A |
| OpenBSD kernel crash through TSS handling, as caused by the crashme program. | ||||
| CVE-2005-0356 | 9 Alaxala, Cisco, F5 and 6 more | 76 Alaxala Networks, Agent Desktop, Aironet Ap1200 and 73 more | 2025-04-03 | N/A |
| Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old. | ||||
| CVE-1999-0798 | 5 Bsdi, Freebsd, Openbsd and 2 more | 7 Bsd Os, Freebsd, Openbsd and 4 more | 2025-04-03 | N/A |
| Buffer overflow in bootpd on OpenBSD, FreeBSD, and Linux systems via a malformed header type. | ||||
| CVE-1999-1225 | 5 Digital, Linux, Netbsd and 2 more | 5 Ultrix, Linux Kernel, Netbsd and 2 more | 2025-04-03 | N/A |
| rpc.mountd on Linux, Ultrix, and possibly other operating systems, allows remote attackers to determine the existence of a file on the server by attempting to mount that file, which generates different error messages depending on whether the file exists or not. | ||||
| CVE-2000-0750 | 3 Netbsd, Openbsd, Redhat | 3 Netbsd, Openbsd, Linux | 2025-04-03 | N/A |
| Buffer overflow in mopd (Maintenance Operations Protocol loader daemon) allows remote attackers to execute arbitrary commands via a long file name. | ||||
| CVE-2000-0995 | 1 Openbsd | 1 Openbsd | 2025-04-03 | N/A |
| Format string vulnerability in OpenBSD yp_passwd program (and possibly other BSD-based operating systems) allows attackers to gain root privileges a malformed name. | ||||
| CVE-2001-0284 | 1 Openbsd | 1 Openbsd | 2025-04-03 | N/A |
| Buffer overflow in IPSEC authentication mechanism for OpenBSD 2.8 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary commands via a malformed Authentication header (AH) IPv4 option. | ||||
| CVE-2001-0572 | 3 Openbsd, Redhat, Ssh | 3 Openssh, Linux, Ssh | 2025-04-03 | N/A |
| The SSH protocols 1 and 2 (aka SSH-2) as implemented in OpenSSH and other packages have various weaknesses which can allow a remote attacker to obtain the following information via sniffing: (1) password lengths or ranges of lengths, which simplifies brute force password guessing, (2) whether RSA or DSA authentication is being used, (3) the number of authorized_keys in RSA authentication, or (4) the lengths of shell commands. | ||||
| CVE-2024-29937 | 2 Freebsd, Openbsd | 2 Freebsd, Openbsd | 2025-03-13 | 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-2023-27567 | 1 Openbsd | 1 Openbsd | 2025-03-06 | 7.5 High |
| In OpenBSD 7.2, a TCP packet with destination port 0 that matches a pf divert-to rule can crash the kernel. | ||||
| CVE-2022-48437 | 1 Openbsd | 2 Libressl, Openbsd | 2025-02-10 | 5.3 Medium |
| 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. | ||||
| CVE-2021-46880 | 1 Openbsd | 2 Libressl, Openbsd | 2025-02-07 | 9.8 Critical |
| 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. | ||||
| CVE-2023-35784 | 1 Openbsd | 2 Libressl, Openbsd | 2024-12-17 | 9.8 Critical |
| A double free or use after free could occur after SSL_clear in OpenBSD 7.2 before errata 026 and 7.3 before errata 004, and in LibreSSL before 3.6.3 and 3.7.x before 3.7.3. NOTE: OpenSSL is not affected. | ||||
| CVE-2024-11148 | 1 Openbsd | 1 Openbsd | 2024-12-06 | 7.5 High |
| In OpenBSD 7.4 before errata 006 and OpenBSD 7.3 before errata 020, httpd(8) is vulnerable to a NULL dereference when handling a malformed fastcgi request. | ||||
| CVE-2023-48795 | 43 9bis, Apache, Apple and 40 more | 78 Kitty, Sshd, Sshj and 75 more | 2024-12-02 | 5.9 Medium |
| The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.

| A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period. | ||||
| CVE-2023-52558 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 7.5 High |
| In OpenBSD 7.4 before errata 002 and OpenBSD 7.3 before errata 019, a network buffer that had to be split at certain length that could crash the kernel after receiving specially crafted escape sequences. | ||||
| CVE-2023-51767 | 3 Fedoraproject, Openbsd, Redhat | 3 Fedora, Openssh, Enterprise Linux | 2024-11-21 | 7.0 High |
| OpenSSH through 9.6, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges. | ||||
