Debian DLA-1552-1 : ghostscript security update

Medium Nessus Plugin ID 118313

Synopsis

The remote Debian host is missing a security update.

Description

This is a follow-up update for the recently discovered -dSAFER issues reported by Tavis Ormandy.

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

For Debian 8 'Jessie', these problems have been fixed in version 9.06~dfsg-2+deb8u11.

We recommend that you upgrade your ghostscript packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
