Created openjpeg tracking bugs for this issue:

Affects: fedora-all [bug 1299775]
Affects: epel-6 [bug 1299777]
Affects: epel-7 [bug 1299778]

Comment 2 Andrej Nemec 2016-01-19 09:33:17 UTC
Created mingw-openjpeg tracking bugs for this issue:

Affects: fedora-all [bug 1299776]

Comment 3 Sandro Mani 2016-09-18 08:23:17 UTC
The functions affected by the vulnerability do not exist in openjpeg 1.x, so this is actually NOTABUG. What is the correct way to close this bug and dependent bugs?

Comment 4 Sandro Mani 2016-09-18 12:03:28 UTC
Closing since this vulnerability does not affect openjpeg 1.x (the affected functions to not exist in openjpeg 1.x).

Comment 5 Martin Prpič 2016-09-20 14:57:21 UTC

While that's true for openjpeg, we were missing openjpeg2 and mingw-openjpeg2 from the list of affected packages. Re-opening this flaw; tracking bugs for Fedora/EPEL have been filed.

Comment 9 Doran Moppert 2016-09-21 00:26:56 UTC
I am unable to reproduce the crash on current Fedora openjpeg, however discussion in the upstream patch talks about fixing integer overflow issues associated with use of opj_int_ceildiv.

See also bug 1299767 (same upstream ticket) and bug 1374329 comment #14 which may be related.
