Ubuntu Security Notice USN-4034-1
June 25, 2019
imagemagick vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 19.04
– Ubuntu 18.10
– Ubuntu 18.04 LTS
– Ubuntu 16.04 LTS
Summary:
Several security issues were fixed in ImageMagick.
Software Description:
– imagemagick: Image manipulation programs and library
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.

The problem can be corrected by updating your system to the following
