DATE CVE VULNERABILITY TITLE RISK
2018-08-28 CVE-2018-15919 Information Exposure vulnerability in multiple products
Remotely observable behaviour in auth-gss2.c in OpenSSH through 7.8 could be used by remote attackers to detect existence of users on a target system when GSS2 is in use.

openbsd netapp CWE-200
5.3
2018-08-17 CVE-2018-15473 Race Condition vulnerability in multiple products
OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c.

2017-10-26 CVE-2017-15906 Incorrect Permission Assignment for Critical Resource vulnerability in multiple products
The process_open function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write operations in readonly mode, which allows attackers to create zero-length files.

2017-02-13 CVE-2016-6210 Information Exposure vulnerability in Openbsd Openssh
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.

openbsd CWE-200
5.9
2017-01-05 CVE-2016-10011 Key Management Errors vulnerability in Openbsd Openssh
authfile.c in sshd in OpenSSH before 7.4 does not properly consider the effects of realloc on buffer contents, which might allow local users to obtain sensitive private-key information by leveraging access to a privilege-separated child process.

openbsd CWE-320
5.5
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-2016-0777 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.
