CVE-2019-12973

In OpenJPEG 2.3.1, there is excessive iteration in the
opj_t1_encode_cblks function of openjp2/t1.c. Remote attackers could
leverage this vulnerability to cause a denial of service via a crafted
bmp file. This issue is similar to CVE-2018-6616.

CVE-2020-6851

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.

CVE-2020-8112

opj_t1_clbl_decode_processor in openjp2/t1.c in OpenJPEG 2.3.1 through
2020-01-28 has a heap-based buffer overflow in the qmfbid==1 case, a
different issue than CVE-2020-6851.

CVE-2020-15389

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.

For Debian 9 stretch, these problems have been fixed in version
2.1.2-1.1+deb9u5.

We recommend that you upgrade your openjpeg2 packages.
