This update for ImageMagick fixes the following issues:

The following security vulnerabilities were fixed:

• CVE-2018-16329: Prevent NULL pointer dereference in the GetMagickProperty function leading to DoS (bsc#1106858)
• 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)
• CVE-2018-14434: Fixed a memory leak for a colormap in WriteMPCImage (bsc#1102003)
• CVE-2018-14435: Fixed a memory leak in DecodeImage in coders/pcd.c (bsc#1102007)
• CVE-2018-14436: Fixed a memory leak in ReadMIFFImage in coders/miff.c (bsc#1102005)
• CVE-2018-14437: Fixed a memory leak in parse8BIM in coders/meta.c (bsc#1102004)
• Disable PS, PS2, PS3, XPS and PDF coders in default policy.xml (bsc#1105592)
