Summary

FreeRDP from 3.30.0 before 3.32.0 contains a resource exhaustion flaw in its rdpecam client, classified as CWE-20 (Improper Input Validation). The client accepts camera media types that the server never advertised. A malicious RDP server can send a StartStreamsRequest with oversized dimensions, forcing large pending-sample allocations and reconfiguring the local camera through the HAL. A public exploit is linked in the references.
