CVE-2007-3999 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-3999):
  Stack-based buffer overflow in the svcauth_gss_validate function in
  lib/rpc/svc_auth_gss.c in the RPCSEC_GSS RPC library (librpcsecgss) in MIT
  Kerberos 5 (krb5) 1.4 through 1.6.2, as used by the Kerberos administration
  daemon (kadmind) and some third-party applications that use krb5, allows
  remote attackers to cause a denial of service (daemon crash) and probably
  execute arbitrary code via a long string in an RPC message.

seems like the package copied the code from bug 191301 and bug 191479, see attached patch.
