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

• Ubuntu 19.10

Summary

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

Software Description

Details

Paul Manfred and Lukas Schauer discovered that Ghostscript incorrectly
handled certain PostScript files. If a user or automated system were

possibly use this issue to access arbitrary files, execute arbitrary code,
or cause a denial of service.
