Description Pedro Sampaio 2017-08-31 17:14:15 UTC 
A stack-based buffer overflow was discovered in the pgxtoimage function
in bin/jp2/convert.c in OpenJPEG 2.2.0. The vulnerability causes an
out-of-bounds write, which may lead to remote denial of service or
possibly remote code execution.

Comment 2 Huzaifa S. Sidhpurwala 2017-09-04 04:01:37 UTC 
Analysis:

A specially crafted JPG2 file can cause OOB write, which can cause application crash. Code execution seems to be unlikely on modern systems and the way buffer stack is overwritten (via fscanf() as seen from the patch).
Comment 3 Dominik Mierzejewski 2017-10-09 12:26:49 UTC 
Is openjpeg-1.3 (RHEL6) and 1.5.1 (RHEL7) affected at all? I couldn't get 1.5.1's image_to_j2k tool to crash using the exploit image from Novell bugzilla.
