  CVE-2008-0062, CVE-2008-0063, CVE-2008-0947 and CVE-2008-0948.");

  script_tag(name:"impact", value:"- CVE-2008-0062: An unauthenticated remote attacker may cause a
  krb4-enabled KDC to crash, expose information, or execute arbitrary code. Successful exploitation
  of this vulnerability could compromise the Kerberos key database and host security on the KDC
  host.

  - CVE-2008-0063: An unauthenticated remote attacker may cause a krb4-enabled KDC to expose
  information. It is theoretically possible for the exposed information to include secret key data
  on some platforms.

  - CVE 2008-0947: Buffer overflow in the RPC library used by libgssrpc and kadmind in MIT
  Kerberos 5 (krb5) allows remote attackers to execute arbitrary code by triggering a large number
  of open file descriptors.

  - CVE 2008-0948: Buffer overflow in the RPC library (lib/rpc/rpc_dtablesize.c) used by libgssrpc
  and kadmind in MIT Kerberos 5 (krb5) when running on systems whose unistd.h does not define the
  FD_SETSIZE macro, allows remote attackers to cause a denial of service (crash) and possibly
  execute arbitrary code by triggering a large number of open file descriptors.");
