Debian DSA-4294-1 : ghostscript - security update

High Nessus Plugin ID 117504

Synopsis

The remote Debian host is missing a security-related update.

Description

Tavis Ormandy discovered multiple vulnerabilites in Ghostscript, an interpreter for the PostScript language, which could result in the execution of arbitrary code if a malformed Postscript file is processed (despite the dSAFER sandbox being enabled).

Solution

Upgrade the ghostscript packages.

For the stable distribution (stretch), these problems have been fixed in version 9.20~dfsg-3.2+deb9u5.
