USN-4034-1: ImageMagick vulnerabilities
25 June 2019

imagemagick vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:

  o Ubuntu 19.04
  o Ubuntu 18.10
  o Ubuntu 18.04 LTS
  o Ubuntu 16.04 LTS


Several security issues were fixed in ImageMagick.

Software Description

  o imagemagick - Image manipulation programs and library


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.
