| CVE-2013-4548 | 1 Openbsd | 1 Openssh | 2025-04-11 | N/A |
| The mm_newkeys_from_blob function in monitor_wrap.c in sshd in OpenSSH 6.2 and 6.3, when an AES-GCM cipher is used, does not properly initialize memory for a MAC context data structure, which allows remote authenticated users to bypass intended ForceCommand and login-shell restrictions via packet data that provides a crafted callback address. | ||||
| CVE-2011-2895 | 6 Freebsd, Freetype, Netbsd and 3 more | 7 Freebsd, Freetype, Netbsd and 4 more | 2025-04-11 | N/A |
| The LZW decompressor in (1) the BufCompressedFill function in fontfile/decompress.c in X.Org libXfont before 1.4.4 and (2) compress/compress.c in 4.3BSD, as used in zopen.c in OpenBSD before 3.8, FreeBSD, NetBSD 4.0.x and 5.0.x before 5.0.3 and 5.1.x before 5.1.1, FreeType 2.1.9, and other products, does not properly handle code words that are absent from the decompression table when encountered, which allows context-dependent attackers to trigger an infinite loop or a heap-based buffer overflow, and possibly execute arbitrary code, via a crafted compressed stream, a related issue to CVE-2006-1168 and CVE-2011-2896. | ||||
| CVE-2011-5000 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-11 | N/A |
| The ssh_gssapi_parse_ename function in gss-serv.c in OpenSSH 5.8 and earlier, when gssapi-with-mic authentication is enabled, allows remote authenticated users to cause a denial of service (memory consumption) via a large value in a certain length field. NOTE: there may be limited scenarios in which this issue is relevant. | ||||
| CVE-2010-4754 | 4 Apple, Freebsd, Netbsd and 1 more | 4 Mac Os X, Freebsd, Netbsd and 1 more | 2025-04-11 | N/A |
| The glob implementation in libc in FreeBSD 7.3 and 8.1, NetBSD 5.0.2, and OpenBSD 4.7, and Libsystem in Apple Mac OS X before 10.6.8, allows remote authenticated users to cause a denial of service (CPU and memory consumption) via crafted glob expressions that do not match any pathnames, as demonstrated by glob expressions in STAT commands to an FTP daemon, a different vulnerability than CVE-2010-2632. | ||||
| CVE-2023-27567 | 1 Openbsd | 1 Openbsd | 2025-03-06 | 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 | 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 | 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-2023-35784 | 1 Openbsd | 2 Libressl, Openbsd | 2024-12-17 | 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-2023-40216 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 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 | 3 Fedoraproject, Openbsd, Redhat | 9 Fedora, Openssh, Devworkspace and 6 more | 2024-11-21 | 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 | 3 Bgp, Openbgpd, Openbsd | 3 Openbgpd, Openbgpd, Openbsd | 2024-11-21 | 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-2022-27882 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 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 | 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-2021-41581 | 1 Openbsd | 1 Libressl | 2024-11-21 | 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-2021-28041 | 4 Fedoraproject, Netapp, Openbsd and 1 more | 11 Fedora, Cloud Backup, Hci Compute Node and 8 more | 2024-11-21 | 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-2020-26142 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 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-2020-16088 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 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-2020-12062 | 1 Openbsd | 1 Openssh | 2024-11-21 | 7.5 High |
| The scp client in OpenSSH 8.2 incorrectly sends duplicate responses to the server upon a utimes system call failure, which allows a malicious unprivileged user on the remote server to overwrite arbitrary files in the client's download directory by creating a crafted subdirectory anywhere on the remote server. The victim must use the command scp -rp to download a file hierarchy containing, anywhere inside, this crafted subdirectory. NOTE: the vendor points out that "this attack can achieve no more than a hostile peer is already able to achieve within the scp protocol" and "utimes does not fail under normal circumstances. | ||||
| CVE-2019-8460 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 7.5 High |
| OpenBSD kernel version <= 6.5 can be forced to create long chains of TCP SACK holes that causes very expensive calls to tcp_sack_option() for every incoming SACK packet which can lead to a denial of service. | ||||
| CVE-2019-6724 | 4 Apple, Barracuda, Linux and 1 more | 4 Mac Os X, Vpn Client, Linux Kernel and 1 more | 2024-11-21 | N/A |
| The barracudavpn component of the Barracuda VPN Client prior to version 5.0.2.7 for Linux, macOS, and OpenBSD runs as a privileged process and can allow an unprivileged local attacker to load a malicious library, resulting in arbitrary code executing as root. | ||||
