"This update for ImageMagick fixes the following issues :

Security issues fixed :

  - Several coders were vulnerable to remote code execution
    attacks, these coders have now been disabled by default
    but can be re-enabled by editing
    '/etc/ImageMagick-*/policy.xml' (bsc#978061)

  - CVE-2016-3714: Insufficient shell characters filtering
    leads to (potentially remote) code execution

  - CVE-2016-3715: Possible file deletion by using
    ImageMagick's 'ephemeral' pseudo protocol which deletes
    files after reading.

  - CVE-2016-3716: Possible file moving by using
    ImageMagick's 'msl' pseudo protocol with any extension
    in any folder.

  - CVE-2016-3717: Possible local file read by using
    ImageMagick's 'label' pseudo protocol to get content of
    the files from the server.

  - CVE-2016-3718: Possible Server Side Request Forgery
    (SSRF) to make HTTP GET or FTP request.

Bugs fixed :

  - Use external svg loader (rsvg)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
