CVE-2013-7336: Null Pointer Dereference

First published: Tue Mar 18 2014(Updated: )

Description of the problem: Domblkstat is possible even with read-only connection, so whenever migration with spice is done and domblkstat gets called at the same time as qemuMonitorGetSpiceMigrationStatus(), there is certain possibility that the daemon crashes. An unprivileged user able to issue commands to running libvirtd could use this flaw to crash libvirtd and prevent more privileged clients from working correctly. Upstream fix: <a href="http://libvirt.org/git/?p=libvirt.git;a=commit;h=484cc321">http://libvirt.org/git/?p=libvirt.git;a=commit;h=484cc321</a> Acknowledgements: This issue was discovered by Marian Krcmarik of Red Hat.
