NVD Description

Note: Versions mentioned in the description apply to the upstream openjpeg2 package. See Remediation section below for Debian:9 relevant versions.

jp2/opj_decompress.c in OpenJPEG through 2.3.1 has a use-after-free that can be triggered if there is a mix of valid and invalid files in a directory operated on by the decompressor. Triggering a double-free may also be possible. This is related to calling opj_image_destroy twice.

Remediation

Upgrade Debian:9 openjpeg2 to version 2.1.2-1.1+deb9u5 or higher.
