Overview
Affected versions of this package are vulnerable to Infinite loop in the pool_decode_rect function when decoding AVC444 metablocks containing more region rectangles than the preallocated worker array size. An attacker can cause the client to enter an infinite loop, consuming CPU resources and preventing normal operation by sending specially crafted AVC444 graphics updates from a malicious RDP server.
