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-2016-0778 119 DoS Overflow 2016-01-14 2018-10-09
4.6
None Remote High Single system Partial Partial Partial
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.
6 CVE-2016-0777 200 +Info 2016-01-14 2018-10-09
4.0
None Remote Low Single system Partial None None
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.
