This bug is triggered by setting the optimize coding member of the JPEG initialization structure to TRUE. If this flag set it to FALSE, ImageMagick completes without complaint. Wokarround could consist to turn off compression optimization in imagemagick to prevent the stack smash. Please assing me CVE and make a cc to 768369@...s.debian.org. Bastien
