| CVE-2000-1010 | 2 Openbsd, Redhat | 2 Openbsd, Linux | 2026-04-16 | N/A |
| Format string vulnerability in talkd in OpenBSD and possibly other BSD-based OSes allows remote attackers to execute arbitrary commands via a user name that contains format characters. | ||||
| CVE-2001-0268 | 2 Netbsd, Openbsd | 2 Netbsd, Openbsd | 2026-04-16 | N/A |
| The i386_set_ldt system call in NetBSD 1.5 and earlier, and OpenBSD 2.8 and earlier, when the USER_LDT kernel option is enabled, does not validate a call gate target, which allows local users to gain root privileges by creating a segment call gate in the Local Descriptor Table (LDT) with a target that specifies an arbitrary kernel address. | ||||
| CVE-2002-0381 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2026-04-16 | N/A |
| The TCP implementation in various BSD operating systems (tcp_input.c) does not properly block connections to broadcast addresses, which could allow remote attackers to bypass intended filters via packets with a unicast link layer address and an IP broadcast address. | ||||
| CVE-2000-0995 | 1 Openbsd | 1 Openbsd | 2026-04-16 | 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-2004-0219 | 1 Openbsd | 1 Openbsd | 2026-04-16 | N/A |
| isakmpd in OpenBSD 3.4 and earlier allows remote attackers to cause a denial of service (crash) via an ISAKMP packet with a malformed IPSEC SA payload, as demonstrated by the Striker ISAKMP Protocol Test Suite. | ||||
| CVE-1999-0323 | 4 Bsdi, Freebsd, Netbsd and 1 more | 4 Bsd Os, Freebsd, Netbsd and 1 more | 2026-04-16 | N/A |
| FreeBSD mmap function allows users to modify append-only or immutable files. | ||||
| CVE-1999-0727 | 1 Openbsd | 1 Openbsd | 2026-04-16 | N/A |
| A kernel leak in the OpenBSD kernel allows IPsec packets to be sent unencrypted. | ||||
| CVE-2025-61985 | 1 Openbsd | 1 Openssh | 2026-04-15 | 3.6 Low |
| ssh in OpenSSH before 10.1 allows the '\0' character in an ssh:// URI, potentially leading to code execution when a ProxyCommand is used. | ||||
| CVE-2025-61984 | 1 Openbsd | 1 Openssh | 2026-04-15 | 3.6 Low |
| ssh in OpenSSH before 10.1 allows control characters in usernames that originate from certain possibly untrusted sources, potentially leading to code execution when a ProxyCommand is used. The untrusted sources are the command line and %-sequence expansion of a configuration file. (A configuration file that provides a complete literal username is not categorized as an untrusted source.) | ||||
| CVE-2025-67901 | 1 Openbsd | 1 Openbsd | 2026-04-15 | 5.3 Medium |
| openrsync through 0.5.0, as used in OpenBSD through 7.8 and on other platforms, allows a client to cause a server SIGSEGV by specifying a length of zero for block data, because the relationship between p->rem and p->len is not checked. | ||||
| CVE-2024-43688 | 2 Openbsd, Vixie | 2 Openbsd, Cron | 2026-04-15 | 7.3 High |
| cron/entry.c in vixie cron before 9cc8ab1, as used in OpenBSD 7.4 and 7.5, allows a heap-based buffer underflow and memory corruption. NOTE: this issue was introduced during a May 2023 refactoring. | ||||
| CVE-2026-35414 | 1 Openbsd | 1 Openssh | 2026-04-10 | 4.2 Medium |
| OpenSSH before 10.3 mishandles the authorized_keys principals option in uncommon scenarios involving a principals list in conjunction with a Certificate Authority that makes certain use of comma characters. | ||||
| CVE-2026-35386 | 1 Openbsd | 1 Openssh | 2026-04-07 | 3.6 Low |
| In OpenSSH before 10.3, command execution can occur via shell metacharacters in a username within a command line. This requires a scenario where the username on the command line is untrusted, and also requires a non-default configurations of % in ssh_config. | ||||
| CVE-2026-35387 | 1 Openbsd | 1 Openssh | 2026-04-07 | 3.1 Low |
| OpenSSH before 10.3 can use unintended ECDSA algorithms. Listing of any ECDSA algorithm in PubkeyAcceptedAlgorithms or HostbasedAcceptedAlgorithms is misinterpreted to mean all ECDSA algorithms. | ||||
| CVE-2026-35388 | 1 Openbsd | 1 Openssh | 2026-04-07 | 2.5 Low |
| OpenSSH before 10.3 omits connection multiplexing confirmation for proxy-mode multiplexing sessions. | ||||
| CVE-2026-35385 | 1 Openbsd | 1 Openssh | 2026-04-03 | 7.5 High |
| In OpenSSH before 10.3, a file downloaded by scp may be installed setuid or setgid, an outcome contrary to some users' expectations, if the download is performed as root with -O (legacy scp protocol) and without -p (preserve mode). | ||||
| CVE-2025-62875 | 4 Openbsd, Opensmtpd, Opensuse and 1 more | 5 Opensmtpd, Opensmtpd, Tumbleweed and 2 more | 2026-01-15 | 5.5 Medium |
| An Improper Check for Unusual or Exceptional Conditions vulnerability in OpenSMTPD allows local users to crash OpenSMTPD. This issue affects openSUSE Tumbleweed: from ? before 7.8.0p0-1.1. | ||||
| CVE-2020-14145 | 3 Netapp, Openbsd, Redhat | 11 Active Iq Unified Manager, Aff A700s, Aff A700s Firmware and 8 more | 2025-12-18 | 5.9 Medium |
| The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected. | ||||
| CVE-2019-6111 | 10 Apache, Canonical, Debian and 7 more | 27 Mina Sshd, Ubuntu Linux, Debian Linux and 24 more | 2025-12-18 | 5.9 Medium |
| An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file). | ||||
| CVE-2019-6110 | 4 Netapp, Openbsd, Siemens and 1 more | 9 Element Software, Ontap Select Deploy, Storage Automation Store and 6 more | 2025-12-18 | 6.8 Medium |
| In OpenSSH 7.9, due to accepting and displaying arbitrary stderr output from the server, a malicious server (or Man-in-The-Middle attacker) can manipulate the client output, for example to use ANSI control codes to hide additional files being transferred. | ||||
