CentOS Errata and Security Advisory CESA-2013:0807
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 guestβs 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:
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.
