Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the progressive_decompress_tile_upgrade process when a mismatch is detected via progressive_rfx_quant_cmp_equal but execution continues after only emitting a warning. An attacker can cause undefined behavior and excessive CPU consumption by supplying crafted input that results in a wrapped value being used as a shift exponent, leading to an extremely large iteration loop.
