From: Baruch Siach Date: Wed, 10 Apr 2019 04:28:19 +0000 (+0300) Subject: package/ghostscript: security bump to version 9.27 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=10a6ea5a305015b6cf7b13591e2e56ba4b75a932;p=buildroot.git package/ghostscript: security bump to version 9.27 Fixes CVE-2019-3835, CVE-2019-3838: A specially crafted PostScript file could use these flaws to have access to the file system outside of the constrains imposed by -dSAFER. Drop upstream patches. Use the make subst function to compute the download site from version.
