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-2015-8325 3 Canonical, Debian, Openbsd 5 Ubuntu Core, Ubuntu Linux, Ubuntu Touch and 2 more 2025-04-12 7.2 HIGH 7.8 HIGH
The do_setup_env function in session.c in sshd in OpenSSH through 7.2p2, when the UseLogin feature is enabled and PAM is configured to read .pam_environment files in user home directories, allows local users to gain privileges by triggering a crafted environment for the /bin/login program, as demonstrated by an LD_PRELOAD environment variable.
CVE-2016-6515 2 Fedoraproject, Openbsd 2 Fedora, Openssh 2025-04-12 7.8 HIGH 7.5 HIGH
The auth_password function in auth-passwd.c in sshd in OpenSSH before 7.3 does not limit password lengths for password authentication, which allows remote attackers to cause a denial of service (crypt CPU consumption) via a long string.
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-2016-0777 5 Apple, Hp, Openbsd and 2 more 7 Mac Os X, Remote Device Access Virtual Customer Access System, Openssh and 4 more 2025-04-12 4.0 MEDIUM 6.5 MEDIUM
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.

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-2014-9424 1 Openbsd 1 Libressl 2025-04-12 7.5 HIGH N/A
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-2016-0778 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-2014-7250 4 Bsd, Freebsd, Netbsd and 1 more 4 Bsd, Freebsd, Netbsd and 1 more 2025-04-12 5.0 MEDIUM N/A
The TCP stack in 4.3BSD Net/2, as used in FreeBSD 5.4, NetBSD possibly 2.0, and OpenBSD possibly 3.6, does not properly implement the session timer, which allows remote attackers to cause a denial of service (resource consumption) via crafted packets.

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."

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.
