Overview
Affected versions of this package are vulnerable to Out-of-bounds Read in the yuv420_context_decode process. An attacker can cause client memory disclosure or crash the client by providing a malicious AVC420 or AVC444 bitstream with a decoded frame smaller than the negotiated surface, leading to out-of-bounds reads during YUV-to-RGB conversion.
