This update incorporates fixes from upstream advisories MITKRB5-SA-2011-001 (standalone kpropd exits if a per-client child exits with an error) and MITKRB5-SA-2011-002 (uninitialized pointer crash in the KDC, hang or crash in the KDC with the LDAP backend).
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.
