This update adds the upstream patch to avoid a potential denial of service in the KDC in versions 1.7 and later (CVE-2010-0283). It obsoletes a previous pending update to version 1.7.1, which incorporates a fix to avoid accidentally tripping account lockout logic on AD servers when the user types in the wrong password.

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.
