If virDomainMemoryStats was run on a domain with virtio balloon driver running on an old qemu which supports QMP but does not support qom-list QMP command, libvirtd would crash. The reason is we did not check if qemuMonitorJSONGetObjectListPaths failed and moreover we even stored its result in an unsigned integer type.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
