Debian DLA-1552-1 : ghostscript security update

high Nessus Plugin ID 118313
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
