Scientific Linux Security Update : ghostscript on SL6.x i386/x86_64 (20170104)

critical Nessus Plugin ID 96301

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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)

Solution

Update the affected packages.
