Description

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. They can be re-enabled by exporting the following environment variable MAGICK_CODER_MODULE_PATH=/usr/lib64/ImageMagick-6.4.3/mo dules-Q16/coders/vu lnerable/ (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)
