CVE-2020-6851

Published: 13 January 2020

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.

From the Ubuntu Security Team

It was discovered that OpenJPEG did not properly handle certain input. If OpenJPEG were supplied with specially crafted input, it could be made to crash or possibly execute arbitrary code.
