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 .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)

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 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 .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)

    specially crafted Postscript file would potentially leak
    sensitive information to an attacker. (CVE-2013-5653,

  - An incorrect reference count was found in .setdevice.
    This issue lead to a use-after-free scenario, which
    could have been exploited for denial-of-service or,
    possibly, arbitrary code execution attacks.
    (CVE-2016-7978, bsc#1001951)

  - Insufficient validation of the type of input in

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)

    ?id=1382294) - *various userparams allow %pipe% in
    paths, allowing remote shell*

  -

    ?id=1382305) - *Type confusion in .initialize_dsc_parser
    allows remote code execution*

----------- #### INFORMATION FOR FEDORA PACKAGERS & MAINTAINERS :

**ghostscript** has been rebased to latest upstream version (9.20).
Rebase notes :

  - **no API/ABI changes between versions 9.16 -> 9.20
    according to upstream**

  - *OpenJPEG* support has been retained

  - *ijs-config* custom tool from upstream has been
    *removed* (by upstream) (*pkg-config* is used by default
    now instead, see [commit
    0c176a9](http://git.ghostscript.com/?p=ghostpdl.git;h=0c
    176a91d53c85cda))

  - some patches were updated to 'git format-patch' format &
    renamed

  - rest of the patches were deleted (irrelevant for current
    version), mostly because upstream has fixed those issues
    in some way

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as
possible without introducing additional issues."
