The vulnerabilities are caused due to an array indexing error within the "azalia_query_devinfo()" function in src/sys/dev/pci/azalia.c and the "hdaudio_afg_query_devinfo()" function in src/sys/dev/pci/hdaudio/hdaudio_afg.c, which can be exploited to e.g. cause a kernel crash. Successful exploitation requires that at least one azalia(4) or hdaudio(4) device is available and configured. SOLUTION: Fixed in the CVS repository. See vendor's advisory for details. PROVIDED AND/OR DISCOVERED BY: The vendor credits Pierre Pronchery.
