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
updates.

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.
(CVE-2012-5532)

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
machines.
