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: incorrect access checking in temp file handling to disclose contents of files (699658)
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use incorrect access checking in temp file handling to disclose contents of files on the system otherwise not readable.
It was discovered that the ghostscript did not properly restrict access to files open prior to enabling the -dSAFER mode. An attacker could possibly exploit this to bypass the -dSAFER protection and disclose the content of affected files 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.
