libvirt.c in the API in Red Hat libvirt 0.8.8 does not properly restrict operations in a read-only connection, which allows remote attackers to cause a denial of service (host OS crash) or possibly execute arbitrary code via a (1) virNodeDeviceDettach, (2) virNodeDeviceReset, (3) virDomainRevertToSnapshot, (4) virDomainSnapshotDelete, (5) virNodeDeviceReAttach, or (6) virConnectDomainXMLToNative call, a different vulnerability than CVE-2008-5086.
