RHSA-2009:0382Red Hat Security Advisory: libvirt security update2009-03-19csaf · redhat_csafUS
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. [Updated 5th May 2011] After installing this update and restarting the libvirtd service, the "virsh attach-disk" command failed. Rebooting guest systems after installing the update resolved the issue. The erratum text has been updated to reflect that guest systems must be rebooted. Future updates will advise if a guest reboot is needed. No changes have been made to the packages.
