Scientific Linux Security Update : hypervkvpd on SL5.x i386/x86_64 (20130509)

medium Nessus Plugin ID 66371
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.

Solution

Update the affected hypervkvpd and / or hypervkvpd-debuginfo packages.
