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.
