CVE-2026-106582 1 Openbsd 1 Openssh 2026-10-13 N/A 3.7 LOW
In sshd and ssh in OpenSSH before 10.6, an LZ77 dictionary coder can be used even though this is contraindicated by the arXiv 2609.07709 "Crossing the Streams" findings.
CVE-2026-106584 1 Openbsd 1 Openssh 2026-10-13 N/A 2.5 LOW
In ssh-keygen in OpenSSH before 10.6, certificates could have incorrect expiration times because of Daylight Saving mishandling. There can be a slightly more severe effect on users in certain Antarctic locations.
CVE-2026-106586 1 Openbsd 1 Openssh 2026-10-13 N/A 2.5 LOW
In sshd in OpenSSH before 10.6, the restrict keyword (in authorized_keys) was supposed to be applicable to tunnel forwarding but was not, a different vulnerability than CVE-2026-73283.
CVE-2026-106587 1 Openbsd 1 Openssh 2026-10-09 N/A 3.6 LOW
In sshd in OpenSSH before 10.6, the value "none" for a configuration option is sometimes interpreted as a filename but was intended to mean that a feature is disabled.
CVE-2026-55654 2 Openbsd, Redhat 3 Openssh, Enterprise Linux, Hardened Images 2026-09-24 N/A 3.7 LOW
A flaw was found in OpenSSH. This vulnerability, a heap out-of-bounds read, occurs during the cleanup of GSSAPI (Generic Security Service Application Programming Interface) indicators when a trailing NULL termination is missing in the auth-indicators array. A remote attacker, under specific configurations involving GSSAPI authentication and a Kerberos environment, could exploit this to cause the SSH authentication path to crash or abort. This leads to a denial of service (DoS), impacting the availability of the SSH service.
CVE-2000-0993 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2026-09-23 7.2 HIGH N/A
Format string vulnerability in pw_error function in BSD libutil library allows local users to gain root privileges via a malformed password in commands such as chpass or passwd.
CVE-2000-0992 2 Openbsd, Ssh 2 Openssh, Ssh 2026-09-23 5.0 MEDIUM N/A
Directory traversal vulnerability in scp in sshd 1.2.xx allows a remote malicious scp server to overwrite arbitrary files via a .. (dot dot) attack.
CVE-2000-0994 1 Openbsd 1 Openbsd 2026-09-23 7.2 HIGH N/A
Format string vulnerability in OpenBSD fstat program (and possibly other BSD-based operating systems) allows local users to gain root privileges via the PWD environmental variable.
CVE-2000-0997 2 Netbsd, Openbsd 2 Netbsd, Openbsd 2026-09-23 7.2 HIGH N/A
Format string vulnerabilities in eeprom program in OpenBSD, NetBSD, and possibly other operating systems allows local attackers to gain root privileges.
CVE-2000-0996 1 Openbsd 1 Openbsd 2026-09-23 7.2 HIGH N/A
Format string vulnerability in OpenBSD su program (and possibly other BSD-based operating systems) allows local attackers to gain root privileges via a malformed shell.
CVE-2000-0995 1 Openbsd 1 Openbsd 2026-09-23 7.2 HIGH 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-2000-0914 1 Openbsd 1 Openbsd 2026-09-23 5.0 MEDIUM N/A
OpenBSD 2.6 and earlier allows remote attackers to cause a denial of service by flooding the server with ARP requests.
CVE-2026-35385 1 Openbsd 1 Openssh 2026-09-01 N/A 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-2026-35414 1 Openbsd 1 Openssh 2026-07-24 N/A 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-2026-35387 1 Openbsd 1 Openssh 2026-07-24 N/A 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 2026-07-24 N/A 2.5 LOW
OpenSSH before 10.3 omits connection multiplexing confirmation for proxy-mode multiplexing sessions.
CVE-2026-35386 1 Openbsd 1 Openssh 2026-07-24 N/A 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-2026-55706 1 Openbsd 1 Openbsd 2026-07-13 N/A 5.8 MEDIUM
sppp_pap_input in sys/net/if_spppsubr.c in OpenBSD before 076e2b1 allows authentication bypass via certain zero values for lengths.
CVE-2026-57589 1 Openbsd 1 Openbsd 2026-07-10 N/A 7.4 HIGH
sys/kern/sysv_sem.c in OpenBSD through 7.9 has a use-after-free allowing local privilege escalation to root. This is a context switch use-after-free after tsleep in sys_semget().
CVE-2026-41285 1 Openbsd 1 Openbsd 2026-06-17 N/A 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.
