Fedora: 2018-81ee973d7c Critical: Ghostscript Printing Issue

This package provides useful conversion utilities based on Ghostscript software,

for converting PS, PDF and other document formats between each other.

Ghostscript is a suite of software providing an interpreter for Adobe Systems'

PostScript (PS) and Portable Document Format (PDF) page description languages.

Its primary purpose includes displaying (rasterization & rendering) and printing

of document pages, as well as conversions between different document formats.

This is a security update for `CVE-2018-16802`. It also fixes a printing problem

discovered in one of the previous CVE fixes. NOTE: *Please, be advised that

there's a separate issue related to printing problems, which is connected to

CUPS itself, meaning this update might not completely resolve your printing

issues.* ---- This is a rebase to latest upstream version of `Ghostscript`,

which fixes several high important CVEs recently discovered. It is advised to

update this version as soon as possible. ---- Security fix for CVE-2918-15909

and some other bug fixes.
