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.

Update instructions:

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