Scientific Linux Security Update : hypervkvpd on SL5.x i386/x86_64

This script is Copyright (C) 2013 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

A denial of service flaw was found in the way hypervkvpd processed
certain Netlink messages. A local, unprivileged user in a guest
(running on Microsoft Hyper-V) could send a Netlink message that, when
processed, would cause the guest's hypervkvpd daemon to exit.

This update also fixes the following bug :

- The hypervkvpd daemon did not close the file descriptors
for pool files when they were updated. This could
eventually lead to hypervkvpd crashing with a 'KVP:
Failed to open file, pool: 1' error after consuming all
available file descriptors. With this update, the file
descriptors are closed, correcting this issue.

After installing the update, it is recommended to reboot all guest

Risk factor :

Medium / CVSS Base Score : 4.9
