Double free vulnerability in the ssl_parse_clienthello_use_srtp_ext function in d1_srtp.c in LibreSSL before 2.1.2 allows remote attackers to cause a denial of service or possibly have unspecified other impact by triggering a certain length-verification error during processing of a DTLS handshake. | |||||
CVE-2016-1907 | 1 Openbsd | 1 Openssh | 2025-04-12 | 5.0 MEDIUM | 5.3 MEDIUM |
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-2016-10012 | 1 Openbsd | 1 Openssh | 2025-04-12 | 7.2 HIGH | 7.8 HIGH |
The shared memory manager (associated with pre-authentication compression) in sshd in OpenSSH before 7.4 does not ensure that a bounds check is enforced by all compilers, which might allows local users to gain privileges by leveraging access to a sandboxed privilege-separation process, related to the m_zback and m_zlib data structures. | |||||
CVE-2016-10010 | 1 Openbsd | 1 Openssh | 2025-04-12 | 6.9 MEDIUM | 7.0 HIGH |
sshd in OpenSSH before 7.4, when privilege separation is not used, creates forwarded Unix-domain sockets as root, which might allow local users to gain privileges via unspecified vectors, related to serverloop.c. | |||||
CVE-2016-10009 | 1 Openbsd | 1 Openssh | 2025-04-12 | 7.5 HIGH | 7.3 HIGH |
Untrusted search path vulnerability in ssh-agent.c in ssh-agent in OpenSSH before 7.4 allows remote attackers to execute arbitrary local PKCS#11 modules by leveraging control over a forwarded agent-socket. | |||||
CVE-2016-0778 | 5 Apple, Hp, Openbsd and 2 more | 6 Mac Os X, Virtual Customer Access System, Openssh and 3 more | 2025-04-12 | 4.6 MEDIUM | 8.1 HIGH |
The (1) roaming_read and (2) roaming_write functions in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2, when certain proxy and forward options are enabled, do not properly maintain connection file descriptors, which allows remote servers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact by requesting many forwardings. | |||||
CVE-2015-5352 | 1 Openbsd | 1 Openssh | 2025-04-12 | 4.3 MEDIUM | 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-2015-6564 | 1 Openbsd | 1 Openssh | 2025-04-12 | 6.9 MEDIUM | N/A |
Use-after-free vulnerability in the mm_answer_pam_free_ctx function in monitor.c in sshd in OpenSSH before 7.0 on non-OpenBSD platforms might allow local users to gain privileges by leveraging control of the sshd uid to send an unexpectedly early MONITOR_REQ_PAM_FREE_CTX request. | |||||
CVE-2014-2532 | 2 Openbsd, Oracle | 2 Openssh, Communications User Data Repository | 2025-04-12 | 5.8 MEDIUM | 4.9 MEDIUM |
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. | |||||
CVE-2014-9278 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Fedora | 2025-04-12 | 4.0 MEDIUM | N/A |
The OpenSSH server, as used in Fedora and Red Hat Enterprise Linux 7 and when running in a Kerberos environment, allows remote authenticated users to log in as another user when they are listed in the .k5users file of that user, which might bypass intended authentication requirements that would force a local login. | |||||
CVE-2016-3115 | 2 Openbsd, Oracle | 2 Openssh, Vm Server | 2025-04-12 | 5.5 MEDIUM | 6.4 MEDIUM |
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-2013-2125 | 1 Openbsd | 1 Opensmtpd | 2025-04-12 | 5.0 MEDIUM | N/A |
OpenSMTPD before 5.3.2 does not properly handle SSL sessions, which allows remote attackers to cause a denial of service (connection blocking) by keeping a connection open. | |||||
CVE-2016-8858 | 1 Openbsd | 1 Openssh | 2025-04-12 | 7.8 HIGH | 7.5 HIGH |
The kex_input_kexinit function in kex.c in OpenSSH 6.x and 7.x through 7.3 allows remote attackers to cause a denial of service (memory consumption) by sending many duplicate KEXINIT requests. NOTE: a third party reports that "OpenSSH upstream does not consider this as a security issue." | |||||
CVE-2015-5600 | 1 Openbsd | 1 Openssh | 2025-04-12 | 8.5 HIGH | 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. |
