| CVE-2025-26465 | 4 Debian, Netapp, Openbsd and 1 more | 9 Debian Linux, Active Iq Unified Manager, Ontap and 6 more | 2026-05-12 | 6.8 Medium |
| A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning the attack complexity high. | ||||
| CVE-2024-6387 | 13 Almalinux, Amazon, Apple and 10 more | 85 Almalinux, Amazon Linux, Macos and 82 more | 2026-05-12 | 8.1 High |
| 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-2023-51385 | 3 Debian, Openbsd, Redhat | 5 Debian Linux, Openssh, Enterprise Linux and 2 more | 2026-05-12 | 6.5 Medium |
| In ssh in OpenSSH before 9.6, OS command injection might occur if a user name or host name has shell metacharacters, and this name is referenced by an expansion token in certain situations. For example, an untrusted Git repository can have a submodule with shell metacharacters in a user name or host name. | ||||
| CVE-2023-48795 | 42 9bis, Apache, Apple and 39 more | 77 Kitty, Sshd, Sshj and 74 more | 2026-05-12 | 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.

| CVE-2021-41617 | 6 Fedoraproject, Netapp, Openbsd and 3 more | 15 Fedora, Active Iq Unified Manager, Aff 500f and 12 more | 2026-05-12 | 7.0 High |
| sshd in OpenSSH 6.2 through 8.x before 8.8, when certain non-default configurations are used, allows privilege escalation because supplemental groups are not initialized as expected. Helper programs for AuthorizedKeysCommand and AuthorizedPrincipalsCommand may run with privileges associated with group memberships of the sshd process, if the configuration specifies running the command as a different user. | ||||
| CVE-2026-41285 | 1 Openbsd | 1 Openbsd | 2026-04-28 | 4.3 Medium |
| In OpenBSD through 7.8, the slaacd and rad daemons have an infinite loop when they receive a crafted ICMPv6 Neighbor Discovery (ND) option (over a local network) with length zero, because of an "nd_opt_len * 8 - 2" expression with no preceding check for whether nd_opt_len is zero. | ||||
| CVE-2016-10708 | 5 Canonical, Debian, Netapp and 2 more | 13 Ubuntu Linux, Debian Linux, Cloud Backup and 10 more | 2026-04-28 | 7.5 High |
| sshd in OpenSSH before 7.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c. | ||||
| CVE-2006-5229 | 2 Novell, Openbsd | 2 Suse Linux, Openssh | 2026-04-23 | N/A |
| OpenSSH portable 4.1 on SUSE Linux, and possibly other platforms and versions, and possibly under limited configurations, allows remote attackers to determine valid usernames via timing discrepancies in which responses take longer for valid usernames than invalid ones, as demonstrated by sshtime. NOTE: as of 20061014, it appears that this issue is dependent on the use of manually-set passwords that causes delays when processing /etc/shadow due to an increased number of rounds. | ||||
| CVE-2008-1058 | 1 Openbsd | 1 Openbsd | 2026-04-23 | N/A |
| The tcp_respond function in netinet/tcp_subr.c in OpenBSD 4.1 and 4.2 allows attackers to cause a denial of service (panic) via crafted TCP packets. NOTE: some of these details are obtained from third party information. | ||||
| CVE-2008-1057 | 1 Openbsd | 1 Openbsd | 2026-04-23 | N/A |
| The ip6_check_rh0hdr function in netinet6/ip6_input.c in OpenBSD 4.2 allows attackers to cause a denial of service (panic) via malformed IPv6 routing headers. | ||||
| CVE-2008-1215 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2026-04-23 | N/A |
| Stack-based buffer overflow in the command_Expand_Interpret function in command.c in ppp (aka user-ppp), as distributed in FreeBSD 6.3 and 7.0, OpenBSD 4.1 and 4.2, and the net/userppp package for NetBSD, allows local users to gain privileges via long commands containing "~" characters. | ||||
| CVE-2007-3102 | 3 Fedora Project, Openbsd, Redhat | 3 Fedora Core, Openssh, Enterprise Linux | 2026-04-23 | N/A |
| Unspecified vulnerability in the linux_audit_record_event function in OpenSSH 4.3p2, as used on Fedora Core 6 and possibly other systems, allows remote attackers to write arbitrary characters to an audit log via a crafted username. NOTE: some of these details are obtained from third party information. | ||||
| CVE-2007-1352 | 8 Mandrakesoft, Openbsd, Redhat and 5 more | 14 Mandrake Linux, Mandrake Linux Corporate Server, Mandrake Multi Network Firewall and 11 more | 2026-04-23 | N/A |
| Integer overflow in the FontFileInitTable function in X.Org libXfont before 20070403 allows remote authenticated users to execute arbitrary code via a long first line in the fonts.dir file, which results in a heap overflow. | ||||
| CVE-2007-0343 | 1 Openbsd | 1 Openbsd | 2026-04-23 | N/A |
| OpenBSD before 20070116 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via certain IPv6 ICMP (aka ICMP6) echo request packets. | ||||
| CVE-2008-2476 | 6 Force10, Freebsd, Juniper and 3 more | 6 Ftos, Freebsd, Jnos and 3 more | 2026-04-23 | N/A |
| The IPv6 Neighbor Discovery Protocol (NDP) implementation in (1) FreeBSD 6.3 through 7.1, (2) OpenBSD 4.2 and 4.3, (3) NetBSD, (4) Force10 FTOS before E7.7.1.1, (5) Juniper JUNOS, and (6) Wind River VxWorks 5.x through 6.4 does not validate the origin of Neighbor Discovery messages, which allows remote attackers to cause a denial of service (loss of connectivity) or read private network traffic via a spoofed message that modifies the Forward Information Base (FIB). | ||||
| CVE-2006-6730 | 2 Netbsd, Openbsd | 2 Netbsd, Openbsd | 2026-04-23 | N/A |
| OpenBSD and NetBSD permit usermode code to kill the display server and write to the X.Org /dev/xf86 device, which allows local users with root privileges to reduce securelevel by replacing the System Management Mode (SMM) handler via a write to an SMRAM address within /dev/xf86 (aka the video card memory-mapped I/O range), and then launching the new handler via a System Management Interrupt (SMI), as demonstrated by a write to Programmed I/O port 0xB2. | ||||
| CVE-2007-4305 | 5 Netbsd, Openbsd, Sysjail and 2 more | 5 Netbsd, Openbsd, Sysjail and 2 more | 2026-04-23 | N/A |
| Multiple race conditions in the (1) Sudo monitor mode and (2) Sysjail policies in Systrace on NetBSD and OpenBSD allow local users to defeat system call interposition, and consequently bypass access control policy and auditing. | ||||
| CVE-2009-0689 | 6 Freebsd, K-meleon Project, Mozilla and 3 more | 9 Freebsd, K-meleon, Firefox and 6 more | 2026-04-23 | N/A |
| Array index error in the (1) dtoa implementation in dtoa.c (aka pdtoa.c) and the (2) gdtoa (aka new dtoa) implementation in gdtoa/misc.c in libc, as used in multiple operating systems and products including in FreeBSD 6.4 and 7.2, NetBSD 5.0, OpenBSD 4.5, Mozilla Firefox 3.0.x before 3.0.15 and 3.5.x before 3.5.4, K-Meleon 1.5.3, SeaMonkey 1.1.8, and other products, allows context-dependent attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a large precision value in the format argument to a printf function, which triggers incorrect memory allocation and a heap-based buffer overflow during conversion to a floating-point number. | ||||
| CVE-2009-3572 | 1 Openbsd | 1 Openbsd | 2026-04-23 | N/A |
| OpenBSD 4.4, 4.5, and 4.6, when running on an i386 kernel, does not properly handle XMM exceptions, which allows local users to cause a denial of service (kernel panic) via unspecified vectors. | ||||
| CVE-2006-5052 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2026-04-23 | N/A |
| Unspecified vulnerability in portable OpenSSH before 4.4, when running on some platforms, allows remote attackers to determine the validity of usernames via unknown vectors involving a GSSAPI "authentication abort." | ||||
