Summary
Security update for openssh
Details

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. (bsc#1106163)
  • 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. (bsc#1105010)
  • CVE-2016-10012: Removed pre-auth compression support from the server to prevent possible cryptographic attacks. (bsc#1016370)

Bugs fixed:

  • Fixed failing 'AuthorizedKeysCommand' within a 'Match User' block in sshd_config (bsc#1105180)
