FreeRDP before 3.29.0 (affected versions <= 3.28.0) contains a divide-by-zero vulnerability in the rdpecam camera redirection client. ecam_dev_process_start_streams_request() parses a server-controlled CAM_MEDIA_TYPE_DESCRIPTION from a StartStreamsRequest PDU but validates only Format and Flags, not FrameRateDenominator. When a malicious or compromised RDP server sends a StartStreamsRequest with FrameRateDenominator set to zero, ecam_encoder_context_init() (channels/rdpecam/client/encoding.c) computes FrameRateNumerator / FrameRateDenominator, causing an integer division by zero (SIGFPE) and termination of the FreeRDP client process. Camera redirection must be enabled on the client for the channel to be reachable. Fixed in FreeRDP 3.29.0.
