  Removing the PS decoders is used to harden ImageMagick against security issues within ghostscript. Enabling them might impact security. (bsc#1122033)

  These are two packages that can be selected:

  • ImageMagick-config-6-SUSE: This has the PS decoders disabled.
  • ImageMagick-config-6-upstream: This has the PS decoders enabled.

  Depending on your local needs install either one of them. The default is the -SUSE configuration.

It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program.

Due to a large number of issues discovered in GhostScript that prevent it from being used by ImageMagick safely, the update for Ubuntu 18.10 and Ubuntu 19.04 includes a default policy change that disables support for the Postscript and PDF formats in ImageMagick. This policy can be overridden if necessary by using an alternate ImageMagick policy configuration.

It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into processing a specially crafted file, an attacker could exploit this to cause a denial of service or affect the reliability of the system. The vulnerabilities included memory leaks, buffer overflows, and improper handling of pixel data.
