Description:

This update for cloud-init fixes the following issues:

Security issue fixed:

  • CVE-2019-0816: Fixed the unnecessary extra ssh keys that were added to authorized_keys (bsc#1129124).

Non-security issues fixed:

  • Add cloud-init-renderer-detect.patch (bsc#1154092, bsc#1142988)
  • Short curcuit the conditional for identifying the sysconfig renderer. If we find ifup/ifdown accept the renderer as available.

  • Add cloud-init-break-resolv-symlink.patch (bsc#1151488)
