Summary
Security update for openssh
Details

This update for openssh fixes the following issues:

  • 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-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)

The following non-security issues were fixed:

  • Stop leaking File descriptors (bsc#964336)
  • sftp-client.c returns wrong error code upon failure (bsc#1091396)
  • added pam_keyinit to pam configuration file (bsc#1081947)
