Description

This update for GraphicsMagick fixes the following security issue :

  • CVE-2018-16323: ReadXBMImage left data uninitialized when processing an XBM file that has a negative pixel value. If the affected code was used as a library loaded into a process that includes sensitive information, that information sometimes can be leaked via the image data (bsc#1106855).
