CVE-2023-38283 | 2 Openbgpd, Openbsd | 2 Openbgpd, Openbsd | 2024-02-28 | 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-2023-40216 | 1 Openbsd | 1 Openbsd | 2024-02-28 | 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-2023-35784 | 1 Openbsd | 2 Libressl, Openbsd | 2024-02-28 | 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-2022-48437 | 1 Openbsd | 2 Libressl, Openbsd | 2024-02-28 | 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 | 2024-02-28 | 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-2023-28531 | 2 Netapp, Openbsd | 4 Brocade Fabric Operating System, Hci Bootstrap Os, Solidfire Element Os and 1 more | 2024-02-28 | 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 | 2024-02-28 | 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-2023-27567 | 1 Openbsd | 1 Openbsd | 2024-02-28 | 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-2022-27881 | 1 Openbsd | 1 Openbsd | 2024-02-28 | 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-2022-27882 | 1 Openbsd | 1 Openbsd | 2024-02-28 | 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-2021-41581 | 1 Openbsd | 1 Libressl | 2024-02-28 | 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-2021-41617 | 5 Fedoraproject, Netapp, Openbsd and 2 more | 14 Fedora, Active Iq Unified Manager, Aff 500f and 11 more | 2024-02-28 | 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-2010-4816 | 1 Openbsd | 1 Openbsd | 2024-02-28 | 5.0 MEDIUM | 7.5 HIGH |
It was found in FreeBSD 8.0, 6.3 and 4.9, and OpenBSD 4.6 that a null pointer dereference in ftpd/popen.c may lead to remote denial of service of the ftpd service. | |||||
CVE-2019-25048 | 2 Linux, Openbsd | 2 Linux Kernel, Libressl | 2024-02-28 | 5.8 MEDIUM | 7.1 HIGH |
LibreSSL 2.9.1 through 3.2.1 has a heap-based buffer over-read in do_print_ex (called from asn1_item_print_ctx and ASN1_item_print). | |||||
CVE-2020-26142 | 1 Openbsd | 1 Openbsd | 2024-02-28 | 2.6 LOW | 5.3 MEDIUM |
An issue was discovered in the kernel in OpenBSD 6.6. The WEP, WPA, WPA2, and WPA3 implementations treat fragmented frames as full frames. An adversary can abuse this to inject arbitrary network packets, independent of the network configuration. | |||||
CVE-2019-25049 | 2 Linux, Openbsd | 2 Linux Kernel, Libressl | 2024-02-28 | 5.8 MEDIUM | 7.1 HIGH |
LibreSSL 2.9.1 through 3.2.1 has an out-of-bounds read in asn1_item_print_ctx (called from asn1_template_print_ctx). | |||||
CVE-2021-28041 | 4 Fedoraproject, Netapp, Openbsd and 1 more | 11 Fedora, Cloud Backup, Hci Compute Node and 8 more | 2024-02-28 | 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. | |||||
CVE-2020-14145 | 2 Netapp, Openbsd | 10 Active Iq Unified Manager, Aff A700s, Aff A700s Firmware and 7 more | 2024-02-28 | 4.3 MEDIUM | 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-2020-16088 | 1 Openbsd | 1 Openbsd | 2024-02-28 | 7.5 HIGH | 9.8 CRITICAL |
iked in OpenIKED, as used in OpenBSD through 6.7, allows authentication bypass because ca.c has the wrong logic for checking whether a public key matches. | |||||
CVE-2019-19522 | 1 Openbsd | 1 Openbsd | 2024-02-28 | 7.2 HIGH | 7.8 HIGH |
OpenBSD 6.6, in a non-default configuration where S/Key or YubiKey authentication is enabled, allows local users to become root by leveraging membership in the auth group. This occurs because root's file can be written to /etc/skey or /var/db/yubikey, and need not be owned by root. |
