==========================================================================
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.
