{"schemaVersion":3,"id":"SUSE-SU-2018:3540-1","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Security update for openssh\n\nThis update for openssh fixes the following issues:\n\nSecurity issues fixed:\n\n- 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. (bsc#1106163)\n- 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)\n- 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)\n- 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. (bsc#1105010)\n- CVE-2016-10012: Removed pre-auth compression support from the server to prevent possible cryptographic attacks.  (bsc#1016370)\n\nBugs fixed:\n\n- Fixed failing 'AuthorizedKeysCommand' within a 'Match User' block in sshd_config
