Ubuntu Security Notice USN-3785-1

Posted Oct 4, 2018

Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 3785-1 - Due to a large number of issues discovered in GhostScript that prevent it from being used by ImageMagick safely, this update 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. It was discovered that several memory leaks existed when handling certain images in ImageMagick. An attacker could use this to cause a denial of service. Various other issues were also addressed.
