Fix perms for virConnectDomainXML{To,From}Native (CVE-2013-4401)
|
|
|
|
The virConnectDomainXMLToNative API should require 'connect:write'
|
|
not 'connect:read', since it will trigger execution of the QEMU
|
|
binaries listed in the XML.
|
|
|
|
Also make virConnectDomainXMLFromNative API require a full
|
|
read-write connection and 'connect:write' permission. Although the
|
|
current impl doesn't trigger execution of QEMU, we should not
|
|
rely on that impl detail from an API permissioning POV.
