DATE CVE VULNERABILITY TITLE RISK
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.

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.

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.

7.8
2016-03-22 CVE-2016-3115 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.

2016-01-19 CVE-2016-1907 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Openbsd Openssh
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.
network
low complexity
openbsd CWE-119
5.3
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.

8.1
2016-01-14 CVE-2016-0777 Information Exposure vulnerability in multiple products
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.

6.5
2014-03-18 CVE-2014-2532 Permissions, Privileges, and Access Controls vulnerability in multiple products
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.

high complexity
oracle openbsd CWE-264
4.9
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
2002-07-03 CVE-2002-0639 Integer Overflow or Wraparound vulnerability in Openbsd Openssh
Integer overflow in sshd in OpenSSH 2.9.9 through 3.3 allows remote attackers to execute arbitrary code during challenge response authentication (ChallengeResponseAuthentication) when OpenSSH is using SKEY or BSD_AUTH authentication.
