NVD Description

Note: Versions mentioned in the description apply only to the upstream openjpeg2 package and not the openjpeg2 package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

In OpenJPEG 2.3.0, there is an integer overflow caused by an out-of-bounds left shift in the opj_j2k_setup_encoder function (openjp2/j2k.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted bmp file.
