Description

A flaw was found in FreeRDP. A heap out-of-bounds read vulnerability exists in the `general_ChromaV1ToYUV444` function during AVC444 chroma plane reconstruction. A remote attacker, acting as a malicious Remote Desktop Protocol (RDP) server, can exploit this by sending a specially crafted `RFX_AVC444_BITMAP_STREAM` with specific frame geometry. This can lead to an out-of-bounds memory read, potentially disclosing sensitive heap data to the client or causing a client crash, resulting in a denial of service.
