in the Kerberos GSS-API library which could be used to cause

fixes to instead correctly detect the error and return an error code.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
