## Description

The virTypedParameterArrayClear function in libvirt 0.9.13 does not
properly handle virDomain\* API calls with typed parameters, which might
allow remote authenticated users to cause a denial of service (libvirtd
crash) via an RPC command with nparams set to zero, which triggers an
out-of-bounds read or a free of an invalid pointer.
