ECHO-71A9-4D38-B645 Integer overflow in the HTJ2K decoder (ht_undo_impl) leading to a heap-buffer-overflow. HTJ2K support (OpenEXRCore internal_ht.cpp / ht_undo_impl) was added in 3.4.0; affected range is 3.4.0-3.4.11. The codec does not exist in 3.1.x, so 3.1.13 is not affected (Debian reports only a fixed_version, not the affected range).
