Overview

Affected versions of this package are vulnerable to Division by zero in the ADPCM decoders when the nBlockAlign parameter is set to 0. An attacker can cause a crash by sending a specially crafted Server Audio Formats PDU on the RDPSND channel that sets nBlockAlign to 0, resulting in a division by zero and a SIGFPE (floating point exception).
