CentOS Errata and Security Advisory CESA-2011:0478
The libvirt library is a C API for managing and interacting with the
virtualization capabilities of Linux and other operating systems. In
addition, libvirt provides tools for remotely managing virtualized systems.
A flaw was found in the way libvirtd handled error reporting for concurrent
connections. A remote attacker able to establish read-only connections to
libvirtd on a server could use this flaw to crash libvirtd. (CVE-2011-1486)
All libvirt users are advised to upgrade to these updated packages, which
contain backported patches to resolve this issue. After installing the
updated packages, libvirtd must be restarted (“service libvirtd restart”)
for this update to take effect.
