Suggested advisory:
========================

The updated packages fix a security vulnerability:

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-2020-8112)

Mageia7, x86_64

CVE-2020-8112
https://github.com/uclouvain/openjpeg/issues/1231
$ opj_decompress -i openjpeg_poc2 -o verification.pgm
===========================================
The extension of this file is incorrect.
FOUND poc2. SHOULD BE .jp2
===========================================
[INFO] Start to read j2k main header (884).
[INFO] Main header has been correctly decoded.
[INFO] No decoded area parameters, set the decoded area to the whole image
[INFO] Header of tile 1 / 1 has been read.
Segmentation fault (core dumped)

Updated the three packages and tried the PoC.

$ opj_decompress -i openjpeg_poc2 -o verification.pgm
===========================================
The extension of this file is incorrect.
FOUND poc2. SHOULD BE .jp2
===========================================
[INFO] Start to read j2k main header (884).
[INFO] Main header has been correctly decoded.
[INFO] No decoded area parameters, set the decoded area to the whole image
[ERROR] Integer overflow
[ERROR] Cannot decode tile, memory error
[ERROR] Failed to decode the codestream in the JP2 file
ERROR -> opj_decompress: failed to decode image!

That seems to have trapped the problem - the heap buffer overflow seems to have triggered an integer overflow.  Shall assume that this is within the range of expected outcomes.

Ran a quick series of tests on images following the procedure in https://bugs.mageia.org/show_bug.cgi?id=26141
No regressions encountered.
