| CVE-2002-1420 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 7.2 HIGH | N/A |
| Integer signedness error in select() on OpenBSD 3.1 and earlier allows local users to overwrite arbitrary kernel memory via a negative value for the size parameter, which satisfies the boundary check as a signed integer, but is later used as an unsigned integer during a data copying operation. | |||||
| CVE-2002-0557 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 7.5 HIGH | N/A |
| Vulnerability in OpenBSD 3.0, when using YP with netgroups in the password database, causes (1) rexec or (2) rsh to run another user's shell, or (3) atrun to change to a different user's directory, possibly due to memory allocation failures or an incorrect call to auth_approval(). | |||||
| CVE-2023-27567 | 1 Openbsd | 1 Openbsd | 2025-03-06 | N/A | 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 | N/A | 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 | N/A | 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-2023-51385 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2024-11-21 | N/A | 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-2023-51384 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2024-11-21 | N/A | 5.5 MEDIUM |
| In ssh-agent in OpenSSH before 9.6, certain destination constraints can be incompletely applied. When destination constraints are specified during addition of PKCS#11-hosted private keys, these constraints are only applied to the first key, even if a PKCS#11 token returns multiple keys. | |||||
| CVE-2023-40216 | 1 Openbsd | 1 Openbsd | 2024-11-21 | N/A | 5.5 MEDIUM |
| OpenBSD 7.3 before errata 014 is missing an argument-count bounds check in console terminal emulation. This could cause incorrect memory access and a kernel crash after receiving crafted DCS or CSI terminal escape sequences. | |||||
| CVE-2023-38408 | 2 Fedoraproject, Openbsd | 2 Fedora, Openssh | 2024-11-21 | N/A | 9.8 CRITICAL |
| The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an incomplete fix for CVE-2016-10009. | |||||
| CVE-2023-38283 | 2 Openbgpd, Openbsd | 2 Openbgpd, Openbsd | 2024-11-21 | N/A | 5.3 MEDIUM |
| In OpenBGPD before 8.1, incorrect handling of BGP update data (length of path attributes) set by a potentially distant remote actor may cause the system to incorrectly reset a session. This is fixed in OpenBSD 7.3 errata 006. | |||||
| CVE-2023-35784 | 1 Openbsd | 2 Libressl, Openbsd | 2024-11-21 | N/A | 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-2023-29323 | 2 Openbsd, Opensmtpd | 2 Openbsd, Opensmtpd | 2024-11-21 | N/A | 7.8 HIGH |
| ascii_load_sockaddr in smtpd in OpenBSD before 7.1 errata 024 and 7.2 before errata 020, and OpenSMTPD Portable before 7.0.0-portable commit f748277, can abort upon a connection from a local, scoped IPv6 address. | |||||
| CVE-2023-28531 | 2 Netapp, Openbsd | 4 Brocade Fabric Operating System, Hci Bootstrap Os, Solidfire Element Os and 1 more | 2024-11-21 | N/A | 9.8 CRITICAL |
| ssh-add in OpenSSH before 9.3 adds smartcard keys to ssh-agent without the intended per-hop destination constraints. The earliest affected version is 8.9. | |||||
| CVE-2023-25136 | 3 Fedoraproject, Netapp, Openbsd | 9 Fedora, 500f, 500f Firmware and 6 more | 2024-11-21 | N/A | 6.5 MEDIUM |
| OpenSSH server (sshd) 9.1 introduced a double-free vulnerability during options.kex_algorithms handling. This is fixed in OpenSSH 9.2. The double free can be leveraged, by an unauthenticated remote attacker in the default configuration, to jump to any location in the sshd address space. One third-party report states "remote code execution is theoretically possible." | |||||
| CVE-2022-27882 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| slaacd in OpenBSD 6.9 and 7.0 before 2022-03-22 has an integer signedness error and resultant heap-based buffer overflow triggerable by a crafted IPv6 router advertisement. NOTE: privilege separation and pledge can prevent exploitation. | |||||
| CVE-2022-27881 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| engine.c in slaacd in OpenBSD 6.9 and 7.0 before 2022-02-21 has a buffer overflow triggerable by an IPv6 router advertisement with more than seven nameservers. NOTE: privilege separation and pledge can prevent exploitation. | |||||
| CVE-2021-41617 | 5 Fedoraproject, Netapp, Openbsd and 2 more | 14 Fedora, Active Iq Unified Manager, Aff 500f and 11 more | 2024-11-21 | 4.4 MEDIUM | 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-2021-41581 | 1 Openbsd | 1 Libressl | 2024-11-21 | 4.3 MEDIUM | 5.5 MEDIUM |
| x509_constraints_parse_mailbox in lib/libcrypto/x509/x509_constraints.c in LibreSSL through 3.4.0 has a stack-based buffer over-read. When the input exceeds DOMAIN_PART_MAX_LEN, the buffer lacks '\0' termination. | |||||
| CVE-2021-36368 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2024-11-21 | 2.6 LOW | 3.7 LOW |
| An issue was discovered in OpenSSH before 8.9. If a client is using public-key authentication with agent forwarding but without -oLogLevel=verbose, and an attacker has silently modified the server to support the None authentication option, then the user cannot determine whether FIDO authentication is going to confirm that the user wishes to connect to that server, or that the user wishes to allow that server to connect to a different server on the user's behalf. NOTE: the vendor's position is "this is not an authentication bypass, since nothing is being bypassed. | |||||
| CVE-2021-28041 | 4 Fedoraproject, Netapp, Openbsd and 1 more | 11 Fedora, Cloud Backup, Hci Compute Node and 8 more | 2024-11-21 | 4.6 MEDIUM | 7.1 HIGH |
| ssh-agent in OpenSSH before 8.5 has a double free that may be relevant in a few less-common scenarios, such as unconstrained agent-socket access on a legacy operating system, or the forwarding of an agent to an attacker-controlled host. | |||||
