USN-4193-1: Ghostscript vulnerability

Releases

• Ubuntu 19.10
• Ubuntu 19.04
• Ubuntu 18.04 ESM
• Ubuntu 16.04 ESM

Packages

• 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.
