https://notcve.org/view.php?id=CVE-2020-6851
OpenJPEG through 2.3.1 has a heap-based buffer overflow in opj_t1_clbl_decode_processor in openjp2/t1.c because of lack of opj_j2k_update_image_dimensions validation. OpenJPEG hasta la versión 2.3.1 tiene un desbordamiento de búfer basado en almacenamiento dinámico en opj_t1_clbl_decode_processor en openjp2 / t1.c debido a la falta de validación de opj_j2k_update_image_dimensions. A heap-based buffer overflow flaw was found in openjpeg in the opj_t1_clbl_decode_processor in libopenjp2.so.
