Synopsis: Low: hypervkvpd security and bug fix update
Advisory ID: SLSA-2013:0807-1
Issue Date: 2013-05-09
CVE Numbers: CVE-2012-5532
--

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.
