For the web cluster serving all content under the domain www.ibiblio.org, we have put in a restrictive policy.xml file for ImageMagick to limit the threat from vulnerabilities that were made public yesterday. Very few users will be impacted, but if your site uses ImageMagick and stopped working as of three hours before this post, this is why. Please let us know the path to your collection and we’ll do our best to find a resolution.
