Red Hat: 2013:0199-01: libvirt: Important Advisory
Summary
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 remote management of virtualized
systems.
A flaw was found in the way libvirtd handled connection cleanup (when a
connection was being closed) under certain error conditions. A remote
attacker able to establish a read-only connection to libvirtd could use
this flaw to crash libvirtd or, potentially, execute arbitrary code with
the privileges of the root user. (CVE-2013-0170)
This issue was discovered by Tingting Zheng of Red Hat.
All users of libvirt are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. After installing
the updated packages, libvirtd will be restarted automatically.
Summary
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
