Summary: Updated libvirt packages that fix two security issues are now available for Red Hat Enterprise Linux 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: RHEL Desktop Multi OS (v. 5 client) - i386, x86_64 RHEL Virtualization (v. 5 server) - i386, ia64, x86_64 3. Description: libvirt is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. libvirt also provides tools for remotely managing virtualized systems. The libvirtd daemon was discovered to not properly check user connection permissions before performing certain privileged actions, such as requesting migration of an unprivileged guest domain to another system. A local user able to establish a read-only connection to libvirtd could use this flaw to perform actions that should be restricted to read-write connections. (CVE-2008-5086) libvirt_proxy, a setuid helper application allowing non-privileged users to communicate with the hypervisor, was discovered to not properly validate user requests. Local users could use this flaw to cause a stack-based buffer overflow in libvirt_proxy, possibly allowing them to run arbitrary code with root privileges. (CVE-2009-0036) All users are advised to upgrade to these updated packages, which contain backported patches which resolve these issues. After installing the update, libvirtd must be restarted manually (for example, by issuing a "service libvirtd restart" command) for this change to take effect. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 476560 - CVE-2008-5086 libvirt: missing checks for read-only connection 484947 - CVE-2009-0036 libvirt: libvirt_proxy buffer overflow 6.
