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.
