Cross-References:   CVE-2012-2669

   An update that fixes one vulnerability is now available.

Description:

   This update fixes the following issues for Hyper-V: The
   source code without this patch caused hv_kvp_daemon to exit
   when it processed a spoofed Netlink packet which has been
   sent from an untrusted local user. Now Netlink messages
   with a non-zero nl_pid source address are ignored and a
   warning is printed into the syslog.

   This fixes the previous change from CVE-2012-2669.
