CVE-2018-11645 Ghostscript vulnerabilities
Title: Ghostscript vulnerabilities
Summary: Several security issues were fixed in Ghostscript.
Tavis Ormandy discovered multiple security issues in Ghostscript. If a user
or automated system were tricked into processing a specially crafted file,
a remote attacker could possibly use these issues to access arbitrary
files, execute arbitrary code, or cause a denial of service.
Instructions: In general, a standard system update will make all the necessary changes.

ghostscript: shading_param incomplete type checking (699660)
In Artifex Ghostscript 9.23 before 2018-08-24, a type confusion using the .shfill operator could be used by attackers able to supply crafted PostScript files to crash the interpreter or potentially execute code.
It was discovered that the ghostscript .shfill operator did not properly validate certain types. An attacker could possibly exploit this to bypass the -dSAFER protection and crash ghostscript or, possibly, execute arbitrary code in the ghostscript context via a specially crafted PostScript document.
Statement: This issue affects the versions of ghostscript as shipped with Red Hat Enterprise Linux 5, 6, and 7.
Red Hat Enterprise Linux 6 is now in Maintenance Support 2 Phase of the support and maintenance life cycle. Thi
