ghostscript vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

– Ubuntu 19.10
– Ubuntu 19.04
– Ubuntu 18.04 LTS
– Ubuntu 16.04 LTS

Summary:

Ghostscript could be made to crash, access files, or run programs if it
opened a specially crafted file.

Software Description:
– ghostscript: PostScript and PDF interpreter

Details:

Paul Manfred and Lukas Schauer 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 access arbitrary files, execute arbitrary code,
or cause a denial of service.
