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. CREATE(Triage):(User=admin) [CVE-2020-15389|https://nvd.nist.gov/vuln/detail/CVE-2020-15389]
