A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol (RDP). A remote attacker can exploit a size_t underflow vulnerability in the IMA-ADPCM and MS-ADPCM audio decoders by sending specially crafted audio data over the RDPSND audio channel. This underflow leads to a heap-buffer-overflow write, which can result in a denial of service for the FreeRDP client.
