| CVE-2016-6242 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| OpenBSD 5.8 and 5.9 allows local users to cause a denial of service (assertion failure and kernel panic) via a large ident value in a kevent system call. | ||||
| CVE-2016-6243 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| thrsleep in kern/kern_synch.c in OpenBSD 5.8 and 5.9 allows local users to cause a denial of service (kernel panic) via a crafted value in the tsp parameter of the __thrsleep system call. | ||||
| CVE-2016-6245 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| OpenBSD 5.8 and 5.9 allows local users to cause a denial of service (kernel panic) via a large size in a getdents system call. | ||||
| CVE-2015-7687 | 2 Fedoraproject, Openbsd | 2 Fedora, Opensmtpd | 2025-04-20 | N/A |
| Use-after-free vulnerability in OpenSMTPD before 5.7.2 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via vectors involving req_ca_vrfy_smtp and req_ca_vrfy_mta. | ||||
| CVE-2016-6241 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| Integer overflow in the amap_alloc1 function in OpenBSD 5.8 and 5.9 allows local users to execute arbitrary code with kernel privileges via a large size value. | ||||
| CVE-2016-6240 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| Integer truncation error in the amap_alloc function in OpenBSD 5.8 and 5.9 allows local users to execute arbitrary code with kernel privileges via a large size value. | ||||
| CVE-2016-6210 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-20 | N/A |
| sshd in OpenSSH before 7.3, when SHA256 or SHA512 are used for user password hashing, uses BLOWFISH hashing on a static password when the username does not exist, which allows remote attackers to enumerate users by leveraging the timing difference between responses when a large password is provided. | ||||
| CVE-2017-1000373 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| The OpenBSD qsort() function is recursive, and not randomized, an attacker can construct a pathological input array of N elements that causes qsort() to deterministically recurse N/4 times. This allows attackers to consume arbitrary amounts of stack memory and manipulate stack memory to assist in arbitrary code execution attacks. This affects OpenBSD 6.1 and possibly earlier versions. | ||||
| CVE-2017-1000372 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| A flaw exists in OpenBSD's implementation of the stack guard page that allows attackers to bypass it resulting in arbitrary code execution using setuid binaries such as /usr/bin/at. This affects OpenBSD 6.1 and possibly earlier versions. | ||||
| CVE-2016-6522 | 1 Openbsd | 1 Openbsd | 2025-04-20 | N/A |
| Integer overflow in the uvm_map_isavail function in uvm/uvm_map.c in OpenBSD 5.9 allows local users to cause a denial of service (kernel panic) via a crafted mmap call, which triggers the new mapping to overlap with an existing mapping. | ||||
| CVE-2017-8301 | 1 Openbsd | 1 Libressl | 2025-04-20 | N/A |
| LibreSSL 2.5.1 to 2.5.3 lacks TLS certificate verification if SSL_get_verify_result is relied upon for a later check of a verification result, in a use case where a user-provided verification callback returns 1, as demonstrated by acceptance of invalid certificates by nginx. | ||||
| CVE-2016-1908 | 4 Debian, Openbsd, Oracle and 1 more | 10 Debian Linux, Openssh, Linux and 7 more | 2025-04-20 | 9.8 Critical |
| The client in OpenSSH before 7.2 mishandles failed cookie generation for untrusted X11 forwarding and relies on the local X11 server for access-control decisions, which allows remote X11 clients to trigger a fallback and obtain trusted X11 forwarding privileges by leveraging configuration issues on this X11 server, as demonstrated by lack of the SECURITY extension on this X11 server. | ||||
| CVE-2015-6565 | 1 Openbsd | 1 Openssh | 2025-04-12 | N/A |
| sshd in OpenSSH 6.8 and 6.9 uses world-writable permissions for TTY devices, which allows local users to cause a denial of service (terminal disruption) or possibly have unspecified other impact by writing to a device, as demonstrated by writing an escape sequence. | ||||
| CVE-2015-5352 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | N/A |
| The x11_open_helper function in channels.c in ssh in OpenSSH before 6.9, when ForwardX11Trusted mode is not used, lacks a check of the refusal deadline for X connections, which makes it easier for remote attackers to bypass intended access restrictions via a connection outside of the permitted time window. | ||||
| CVE-2015-6563 | 3 Apple, Openbsd, Redhat | 3 Mac Os X, Openssh, Enterprise Linux | 2025-04-12 | N/A |
| The monitor component in sshd in OpenSSH before 7.0 on non-OpenBSD platforms accepts extraneous username data in MONITOR_REQ_PAM_INIT_CTX requests, which allows local users to conduct impersonation attacks by leveraging any SSH login access in conjunction with control of the sshd uid to send a crafted MONITOR_REQ_PWNAM request, related to monitor.c and monitor_wrap.c. | ||||
| CVE-2016-1907 | 1 Openbsd | 1 Openssh | 2025-04-12 | N/A |
| The ssh_packet_read_poll2 function in packet.c in OpenSSH before 7.1p2 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via crafted network traffic. | ||||
| CVE-2016-3115 | 3 Openbsd, Oracle, Redhat | 3 Openssh, Vm Server, Enterprise Linux | 2025-04-12 | N/A |
| Multiple CRLF injection vulnerabilities in session.c in sshd in OpenSSH before 7.2p2 allow remote authenticated users to bypass intended shell-command restrictions via crafted X11 forwarding data, related to the (1) do_authenticated1 and (2) session_x11_req functions. | ||||
| CVE-2015-5600 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | N/A |
| The kbdint_next_device function in auth2-chall.c in sshd in OpenSSH through 6.9 does not properly restrict the processing of keyboard-interactive devices within a single connection, which makes it easier for remote attackers to conduct brute-force attacks or cause a denial of service (CPU consumption) via a long and duplicative list in the ssh -oKbdInteractiveDevices option, as demonstrated by a modified client that provides a different password for each pam element on this list. | ||||
| CVE-2016-0777 | 6 Apple, Hp, Openbsd and 3 more | 8 Mac Os X, Remote Device Access Virtual Customer Access System, Openssh and 5 more | 2025-04-12 | N/A |
| The resend_bytes function in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2 allows remote servers to obtain sensitive information from process memory by requesting transmission of an entire buffer, as demonstrated by reading a private key. | ||||
| CVE-2014-2532 | 3 Openbsd, Oracle, Redhat | 3 Openssh, Communications User Data Repository, Enterprise Linux | 2025-04-12 | N/A |
| sshd in OpenSSH before 6.6 does not properly support wildcards on AcceptEnv lines in sshd_config, which allows remote attackers to bypass intended environment restrictions by using a substring located before a wildcard character. | ||||
