A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol (RDP). A malicious RDP server can exploit this vulnerability by sending specially crafted audio data in IMA ADPCM format with an invalid initial step index value. This unvalidated input can cause the FreeRDP client to crash, leading to a Denial of Service (DoS) for affected users. This issue impacts FreeRDP clients with audio redirection (RDPSND) enabled, which is the default configuration.
