The mem_get_bits_rectangle function in Artifex Software, Inc. Ghostscript 9.20 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted PostScript document.

This update for ghostscript-library fixes several issues. These security issues were fixed :

  - CVE-2017-9726: The Ins_MDRP function in base/ttinterp.c     allowed remote attackers to cause a denial of service     (heap-based buffer over-read and application crash) or     possibly have unspecified other impact via a crafted     document (bsc#1050889)

  - CVE-2017-9727: The gx_ttfReader__Read function in     base/gxttfb.c allowed remote attackers to cause a denial     of service (heap-based buffer over-read and application     crash) or possibly have unspecified other impact via a     crafted document (bsc#1050888)

  - CVE-2017-9739: The Ins_JMPR function in base/ttinterp.c     allowed remote attackers to cause a denial of service     (heap-based buffer over-read and application crash) or     possibly have unspecified other impact via a crafted     document (bsc#1050887)

  - CVE-2017-11714: psi/ztoken.c mishandled references to     the scanner state structure, which allowed remote     attackers to cause a denial of service (application     crash) or possibly have unspecified other impact via a     crafted PostScript document, related to an out-of-bounds     read in the igc_reloc_struct_ptr function in psi/igc.c     (bsc#1051184)

  - CVE-2017-9835: The gs_alloc_ref_array function allowed     remote attackers to cause a denial of service     (heap-based buffer overflow and application crash) or     possibly have unspecified other impact via a crafted     PostScript document (bsc#1050879)

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 Low. 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) :

* A NULL pointer dereference flaw was found in ghostscript's mem_get_bits_rectangle function. A specially crafted postscript document could cause a crash in the context of the gs process.
(CVE-2017-7207)

The remote host is affected by the vulnerability described in GLSA-201708-06 (GPL Ghostscript: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in GPL Ghostscript. Please       review the CVE identifiers referenced below for additional information.
  Impact :

    A context-dependent attacker could entice a user to open a specially       crafted PostScript file or PDF document using GPL Ghostscript possibly       resulting in the execution of arbitrary code with the privileges of the       process or a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

Several issues were found in Ghostscript, the GPL PostScript/PDF interpreter, which allow remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted PostScript document.

For Debian 7 'Wheezy', these problems have been fixed in version 9.05~dfsg-6.3+deb7u7.

We recommend that you upgrade your ghostscript packages.

USN-3272-1 fixed vulnerabilities in Ghostscript. This change introduced a regression when the DELAYBIND feature is used with the eqproc command. This update fixes the problem.

We apologize for the inconvenience.

It was discovered that Ghostscript improperly handled parameters to the rsdparams and eqproc commands. An attacker could use these to craft a malicious document that could disable -dSAFER protections, thereby allowing the execution of arbitrary code, or cause a denial of service (application crash). (CVE-2017-8291)

Kamil Frankowicz discovered a use-after-free vulnerability in the color management module of Ghostscript. An attacker could use this to cause a denial of service (application crash). (CVE-2016-10217)

Kamil Frankowicz discovered a divide-by-zero error in the scan conversion code in Ghostscript. An attacker could use this to cause a denial of service (application crash).
(CVE-2016-10219)

Kamil Frankowicz discovered multiple NULL pointer dereference errors in Ghostscript. An attacker could use these to cause a denial of service (application crash).
(CVE-2016-10220, CVE-2017-5951, CVE-2017-7207).
