Description

It was found that Samba before versions 4.5.3, 4.4.8, 4.3.13 always requested forwardable tickets when using Kerberos authentication. A service to which Samba authenticated using Kerberos could subsequently use the ticket to impersonate Samba to other services or domain users.

Solution(s)

  • samba-upgrade-4_3_13
  • samba-upgrade-4_4_8
  • samba-upgrade-4_5_3
