Debian DSA-4346-1 : ghostscript - security update

critical Nessus Plugin ID 119269

Language:

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-related update.

Description

Several vulnerabilities were discovered in Ghostscript, the GPL PostScript/PDF interpreter, which may result in denial of service or the execution of arbitrary code if a malformed Postscript file is processed (despite the -dSAFER sandbox being enabled).

This update rebases ghostscript for stretch to the upstream version 9.26 which includes additional changes.

Solution

Upgrade the ghostscript packages.

For the stable distribution (stretch), these problems have been fixed in version 9.26~dfsg-0+deb9u1.
