How to fix?

Upgrade Debian:9 openjpeg2 to version 2.1.2-1.1+deb9u6 or higher.

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.

There's a flaw in openjpeg in versions prior to 2.4.0 in src/lib/openjp2/pi.c. When an attacker is able to provide crafted input to be processed by the openjpeg encoder, this could cause an out-of-bounds read. The greatest impact from this flaw is to application availability.
