Description

This update for Kerberos 5 fixes one security issue :

The KDC plugin for PKINIT can dereference a NULL pointer when processing malformed packets, leading to a crash of the KDC process. (bnc#806715, CVE-2013-1415)

Additionally, it improves compatibility with processes that handle large numbers of open files. (bnc#787272)
