Package: imagemagick Version: 8:6.8.9.9-5+deb8u10 Severity: normal Ubuntu imagemagick security updates are based on Debian security updates. The latest round of jessie updates introduced a regression.
Please see the downstream bug report for a reproducer script: https://bugs.launchpad.net/ubuntu/+source/imagemagick/+bug/1707015 I've tracked this down to the 0224-Ensure-token-does-not-overflow.patch patch, but I haven't come up with a fix yet.
