Description: The Ghostscript suite contains utilities for rendering PostScript and PDF 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): * Previously, ghostscript-9.07-31.el7_6.1 introduced a regression during the standard input reading, causing a "/invalidfileaccess in --run--" error. With this update, the regression has been fixed and the described error no longer occurs. (BZ#1665919) 4.
