Description Agostino Sarubbo gentoo-dev 2014-11-06 13:55:37 UTC
From ${URL} :

In at least the qemu implementation of virDomainGetXMLDesc, the use
of the flag VIR_DOMAIN_XML_MIGRATABLE (which is usable from a
read-only connection) triggers the implicit use of
VIR_DOMAIN_XML_SECURE prior to calling qemuDomainFormatXML.
However, the use of VIR_DOMAIN_XML_SECURE is supposed to be restricted
to read-write clients only.  

A remote attacker able to establish a read-only connection to libvirtd
could use this flaw to cause leak certain limited information from the
domain xml file.


@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
