NVD Description

Note: Versions mentioned in the description apply only to the upstream samba4-pidl package and not the samba4-pidl package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

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.
