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.
