A vulnerability was found in a way OpenJpeg parses certain JPEG 2000 image files. While parsing a specially crafted file, function opj_tgt_reset can cause a segmentation fault. Original source with reproducer attached: http://seclists.org/oss-sec/2016/q1/128

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?
Closing since this vulnerability does not affect openjpeg 1.x (the affected functions to not exist in openjpeg 1.x).

(In reply to Sandro Mani from comment #4) > Closing since this vulnerability does not affect openjpeg 1.x (the affected > functions to not exist in openjpeg 1.x). 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.
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.
