Details

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.
