+Submitted By: Ken Moffat <ken at linuxfromscratch dot org>
+Date: 2018-10-08
+Initial Package Version: 20180414
+Upstream Status: Applied
+Origin: Upstream
+Description: Three fixes, cherry-picked from svn plus a CVE fix.
+
+r47469 Fix segfault in dvipdfm-x (XeTeX) on 1/2/4-bit transparent indexed PNGs.
+
+r47470 Support poppler-0.64.0 (this one is critical for current BLFS).
+
+r47477 Fix a ptex regression for discontinuous kinsoku table.
+
+Also, via fedora (I got lost in svn) a critical fix for CVE-2018-17407
+
+"A buffer overflow in the handling of Type 1 fonts allows arbitrary code
+execution when a malicious font is loaded by one of the vulnerable tools:
+pdflatex, pdftex, dvips, or luatex."
+
+Then add updated versions of pdftoepdf-newpoppler for poppler-0.68.0 and
+0.69.0 (this should cover all recent versions, and hopefully also covers
+older systems if people update to 2018 because of hte CVE).
