Overview

Affected versions of this package are vulnerable to Out-of-bounds Write in the process_reference_picture_set function. An attacker can cause memory corruption or crash the application by submitting a specially crafted H.265 bitstream that triggers an out-of-bounds write to the PocStFoll array.
