imagemagick regression ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS Summary: USN-3363-1 caused a regression in ImageMagick. Software Description: - imagemagick: Image manipulation programs and library Details: USN-3363-1 fixed vulnerabilities in ImageMagick. The update caused a regression for certain users when processing images. The problematic patch has been reverted pending further investigation. We apologize for the inconvenience. Original advisory details: It was discovered that ImageMagick incorrectly handled certain malformed image files.
