Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 18.10 : ghostscript vulnerabilities (USN-3803-1)

High Nessus Plugin ID 118567

Synopsis

The remote Ubuntu host is missing one or more security-related
patches.

Description

Tavis Ormandy discovered multiple security issues in Ghostscript. If a
user or automated system were tricked into processing a specially
crafted file, a remote attacker could possibly use these issues to
access arbitrary files, execute arbitrary code, or cause a denial of
service.

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

Solution

Update the affected ghostscript and / or libgs9 packages.
