CVE-2018-17961 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.
