Description Petr Matousek 2011-03-09 23:03:06 UTC 
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.
Comment 3 Petr Matousek 2011-03-09 23:11:31 UTC 
Created libvirt tracking bugs for this issue

Affects: fedora-all [bug 683655]
Comment 4 Jim Fehlig 2011-03-10 17:42:20 UTC 
Should virNodeDeviceReAttach also be added to the list?

> Should virNodeDeviceReAttach also be added to the list?

Yes, I omitted it by mistake. Thanks Jim.
