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.
network
low complexity
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.
5.3
2018-01-21 CVE-2016-10708 NULL Pointer Dereference vulnerability in multiple products
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.
network
low complexity
openbsd debian canonical netapp CWE-476
7.5
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.

low complexity
openbsd oracle debian netapp redhat CWE-732
5.3
2017-04-11 CVE-2016-1908 Improper Authentication vulnerability in multiple products
The client in OpenSSH before 7.2 mishandles failed cookie generation for untrusted X11 forwarding and relies on the local X11 server for access-control decisions, which allows remote X11 clients to trigger a fallback and obtain trusted X11 forwarding privileges by leveraging configuration issues on this X11 server, as demonstrated by lack of the SECURITY extension on this X11 server.

9.8
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.
network
high complexity
openbsd CWE-200
5.9
2017-01-05 CVE-2016-10012 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Openbsd Openssh
The shared memory manager (associated with pre-authentication compression) in sshd in OpenSSH before 7.4 does not ensure that a bounds check is enforced by all compilers, which might allows local users to gain privileges by leveraging access to a sandboxed privilege-separation process, related to the m_zback and m_zlib data structures.
local
low complexity
openbsd CWE-119
7.8
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.
local
low complexity
openbsd CWE-320
5.5
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
