DATE CVE VULNERABILITY TITLE RISK
2017-01-05 CVE-2016-10010 Permissions, Privileges, and Access Controls vulnerability in Openbsd Openssh
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.
local
high complexity
openbsd CWE-264
7.0
2017-01-05 CVE-2016-10009 Untrusted Search Path vulnerability in Openbsd Openssh
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.
network
low complexity
openbsd CWE-426
7.3
2016-12-09 CVE-2016-8858 Resource Management Errors vulnerability in Openbsd Openssh
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.
network
low complexity
openbsd CWE-399
7.5
2016-08-07 CVE-2016-6515 Improper Input Validation vulnerability in multiple products
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.
network
low complexity
openbsd fedoraproject CWE-20
7.5
2016-05-01 CVE-2015-8325 Permissions, Privileges, and Access Controls vulnerability in multiple products
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.
local
low complexity
debian openbsd canonical CWE-264
7.8
2016-01-14 CVE-2016-0778 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
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.

high complexity
oracle openbsd apple hp sophos CWE-119
8.1
2006-09-27 CVE-2006-5051 Double Free vulnerability in multiple products
Signal handler race condition in OpenSSH before 4.4 allows remote attackers to cause a denial of service (crash), and possibly execute arbitrary code if GSSAPI authentication is enabled, via unspecified vectors that lead to a double-free.
network
high complexity
openbsd debian apple CWE-415
8.1
2004-11-23 CVE-2004-0079 NULL Pointer Dereference vulnerability in multiple products
The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.
