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)
After installing the update, libvirtd must be restarted manually (for example, by issuing a βservice libvirtd restartβ command) for this change to take effect.
