Overview
Affected versions of this package are vulnerable to Buffer Overflow via the openhtj2k_decoder_impl::invoke, invoke_line_based, invoke_line_based_stream, and invoke_line_based_predecoded functions in source/core/interface/decoder.cpp. An attacker can achieve arbitrary code execution by supplying specially crafted input that triggers a buffer overflow during decoding.
