Overview
Affected versions of this package are vulnerable to Out-of-bounds Read in the general_ChromaV1ToYUV444 function during AVC444 chroma plane reconstruction. An attacker can access sensitive information or cause a denial of service by sending a specially crafted RFX_AVC444_BITMAP_STREAM with specific frame geometry that triggers an out-of-bounds memory read past the allocated luma plane.
