Description Petr Matousek 2011-03-09 18:03:06 EST
Description of problem:
It has been found that several libvirt API calls (virNodeDeviceDettach, virNodeDeviceReset, virNodeDeviceReAttach, virDomainRevertToSnapshot, virDomainSnapshotDelete and virConnectDomainXMLToNative) did not honour read-only connection. Local attacker could use this flaw to crash the server (DoS) or possibly escalate his privileges.

Should virNodeDeviceReAttach also be added to the list?
