[Frank Heckenbach]

Package: imagemagick
Version: 8:6.8.9.9-5+deb8u4
Severity: important

After the recent security update, writing PNM files in portrait
format gives wrong results.

Before:

% convert -version
Version: ImageMagick 6.8.9-9 Q16 x86_64 2016-06-01
% convert -geometry 40% tux.png tux-scaled-old.ppm
% convert -average tux-scaled-old.ppm{,} tux-average-old.ppm

After:

% convert -version
Version: ImageMagick 6.8.9-9 Q16 x86_64 2016-08-25
% convert -geometry 40% tux.png tux-scaled-new.ppm
% convert -average tux-scaled-old.ppm{,} tux-average-new.ppm
