Virtuozzo 7 : ghostscript / ghostscript-cups / ghostscript-devel / etc (VZLSA-2017-0013)

critical Nessus Plugin ID 101399

Synopsis

The remote Virtuozzo host is missing a security update.

Description

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

Red Hat Product Security has rated this update as having a security impact of Moderate. 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 the ghostscript functions getenv, filenameforall and .libfile did not honor the -dSAFER option, usually used when processing untrusted documents, leading to information disclosure. A specially crafted postscript document could read environment variable, list directory and retrieve file content respectively, from the target. (CVE-2013-5653, CVE-2016-7977)

* It was found that the ghostscript function .setdevice suffered a use-after-free vulnerability due to an incorrect reference count. A specially crafted postscript document could trigger code execution in the context of the gs process. (CVE-2016-7978)

* It was found that the ghostscript function .initialize_dsc_parser did not validate its parameter before using it, allowing a type confusion flaw. A specially crafted postscript document could cause a crash code execution in the context of the gs process. (CVE-2016-7979)

* It was found that ghostscript did not sufficiently check the validity of parameters given to the .sethalftone5 function. A specially crafted postscript document could cause a crash, or execute arbitrary code in the context of the gs process. (CVE-2016-8602)

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-cups / ghostscript-devel / etc package.
