Details

USN-5224-1 fixed several vulnerabilities in Ghostscript. This update provides
the corresponding update for Ubuntu 16.04 ESM.

Original advisory details:

It was discovered that Ghostscript incorrectly handled certain PostScript
files. If a user or automated system were tricked into processing a
specially crafted file, a remote attacker could possibly use this issue to
cause Ghostscript to crash, resulting in a denial of service, or possibly
execute arbitrary code.
