RHEL 6 / 7 : ghostscript (RHSA-2017:1230)

high Nessus Plugin ID 100172

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

An update for ghostscript is now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

The Ghostscript suite contains utilities for rendering PostScript and PDF documents. Ghostscript translates PostScript code to common bitmap formats so that the code can be displayed or printed.

Security Fix(es) :

* It was found that ghostscript did not properly validate the parameters passed to the .rsdparams and .eqproc functions. During its execution, a specially crafted PostScript document could execute code in the context of the ghostscript process, bypassing the -dSAFER protection. (CVE-2017-8291)

Solution

Update the affected packages.
