1 CVE-2018-15919 200 +Info 2018-08-28 2018-12-22
5.0
None Remote Low Not required Partial None None
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. NOTE: the discoverer states 'We understand that the OpenSSH developers do not want to treat such a username enumeration (or "oracle") as a vulnerability.'
2 CVE-2018-15473 200 +Info 2018-08-17 2018-12-05
5.0
None Remote Low Not required Partial None None
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.
3 CVE-2017-15906 275 2017-10-25 2018-09-11
5.0
None Remote Low Not required None Partial None
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.
4 CVE-2016-10708 476 DoS 2018-01-21 2018-11-07
5.0
None Remote Low Not required None None Partial
sshd in OpenSSH before 7.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c.
5 CVE-2016-6515 20 DoS 2016-08-07 2018-09-11
7.8
None Remote Low Not required None None Complete
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.
6 CVE-2016-6210 200 +Info 2017-02-13 2018-01-04
4.3
None Remote Medium Not required Partial None None
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.
7 CVE-2015-8325 264 +Priv 2016-04-30 2018-06-29
7.2
None Local Low Not required Complete Complete Complete
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.
