FreeRDP versions prior to 3.28.0 contain a vulnerability in the rdpsnd_server_recv_formats function where a malformed Client Audio Formats PDU can cause a double free of memory. This issue can be triggered by an authenticated RDP client, leading to server termination and potential heap corruption. The vulnerability is fixed in version 3.28.0.

FreeRDP, a Remote Desktop Protocol implementation, has a vulnerability in versions prior to 3.28.0 in the rdpsnd_server_recv_formats function located in channels/rdpsnd/server/rdpsnd_main.c. When processing a malformed Client Audio Formats PDU, the function frees context->client_formats without clearing the pointer or num_client_formats, leaving a dangling pointer. Upon session teardown, rdpsnd_server_context_free attempts to free the same memory again, causing a double free. This results in reliable server termination and may cause allocator-dependent heap corruption. The issue is resolved in FreeRDP version 3.28.0.
