documents. Ghostscript translates PostScript code to common bitmap formats
so that the code can be displayed or printed.

Security Fix(es):

* ghostscript: use-after-free in copydevice handling (699661)
(CVE-2018-16540)

* ghostscript: access bypass in psi/zdevice2.c (700153) (CVE-2018-19475)

* ghostscript: access bypass in psi/zicc.c (700169) (CVE-2018-19476)

* ghostscript: access bypass in psi/zfjbig2.c (700168) (CVE-2018-19477)

* ghostscript: subroutines within pseudo-operators must themselves be
pseudo-operators (700317) (CVE-2019-6116)

For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.

Red Hat would like to thank Tavis Ormandy (Google Project Zero) for
reporting CVE-2019-6116.

Bug Fix(es):
