Description

This update updates the package from version 1.9.3 to version 1.9.4, mainly to pick up a fix for an interoperability problem with Windows Server 2008R2 read-only domain controllers, and incorporates the upstream fix for CVE-2012-1015, in which the KDC could be made to attempt to free an uninitialized pointer.

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.
