ghostscript vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 19.10
- Ubuntu 19.04
- Ubuntu 18.04 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.
