|Summary:||The remote host is missing an update for the 'openssh' package(s) announced via the SUSE-SU-2018:3540-1 advisory.|
The remote host is missing an update for the 'openssh' package(s) announced via the SUSE-SU-2018:3540-1 advisory.
This update for openssh fixes the following issues:
Security issues fixed:
CVE-2018-15919: Remotely observable behaviour in auth-gss2.c in OpenSSH
could be used by remote attackers to detect existence of users on a
target system when GSS2 is in use. OpenSSH developers do not want to
treat such a username enumeration (or 'oracle') as a vulnerability.
CVE-2017-15906: The process_open function in sftp-server.c in OpenSSH
did not properly prevent write operations in readonly mode, which
allowed attackers to create zero-length files. (bsc#1065000, bsc#1106726)
CVE-2016-10708: sshd allowed 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. (bsc#1076957)
CVE-2018-15473: OpenSSH was prone to a user existance oracle
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.
CVE-2016-10012: Removed pre-auth compression support from the server to
prevent possible cryptographic attacks. (bsc#1016370)
Fixed failing 'AuthorizedKeysCommand' within a 'Match User' block in
'openssh' package(s) on SUSE Linux Enterprise Server 11-SP3, SUSE Linux Enterprise Point of Sale 11-SP3, SUSE Linux Enterprise Debuginfo 11-SP3
Please install the updated package(s).
