Summary

The remote host is missing an update for the 'hypervkvpd-0' package(s) announced via the referenced advisory.

Insight

Insight

The hypervkvpd package contains hypervkvpd, the guest Microsoft Hyper-V Key-Value Pair (KVP) daemon. The daemon passes basic information to the host through VMBus, such as the guest IP address, fully qualified domain name, operating system name, and operating system release number. 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) The CVE-2012-5532 issue was discovered by Florian Weimer of the Red Hat Product Security Team. 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. (BZ#953502) Users of hypervkvpd are advised to upgrade to this updated package, which contains backported patches to correct these issues. After installing the update, it is recommended to reboot all guest machines.
