Virtuozzo 6 : ghostscript / ghostscript-devel / ghostscript-doc / etc (VZLSA-2018-3760)

high Nessus Plugin ID 144534

Synopsis

The remote Virtuozzo host is missing a security update.

Description

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

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 discovered that the ghostscript /invalidaccess checks fail under certain conditions. An attacker could possibly exploit this to bypass the -dSAFER protection and, for example, execute arbitrary shell commands via a specially crafted PostScript document.
(CVE-2018-16509)

Red Hat would like to thank Tavis Ormandy (Google Project Zero) for reporting this issue.

Note that Tenable Network Security has attempted to extract the preceding description block directly from the corresponding Red Hat security advisory. Virtuozzo provides no description for VZLSA advisories. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected ghostscript / ghostscript-devel / ghostscript-doc / etc package.
