+Subject: [PATCH] robottime: Honor the SOURCE_DATE_EPOCH environment variable.
+
+Honoring the SOURCE_DATE_EPOCH environment variable allows building
+the documentation using libdoc reproducibly, by setting the generated
+timestamp to a fixed value.
+
+For more background on reproducible builds and the SOURCE_DATE_EPOCH
+environment variable, see:
+https://reproducible-builds.org/specs/source-date-epoch/.
+
+* src/robot/utils/robottime.py: import `os'.
+(TimestampCache._get_epoch): Retrieve date from SOURCE_DATE_EPOCH if
+it is defined, otherwise from time.time().
+* utest/output/test_logger.py (TestLogger.test_write_to_one_logger):
+Check for the existance of a timestamp attribute instead of checking
+for its content as the later is easy to break when using the
+SOURCE_DATE_EPOCH environment variable.

+This patch adds support for newer versions of Poppler and some upstream
+TexLive fixes, including one for CVE-2018-17407.
+
+It is taken from Linux From Scratch:
+<http://www.linuxfromscratch.org/patches/blfs/svn/texlive-20180414-source-upstream_fixes-3.patch>.
+
+Submitted By: Ken Moffat <ken at linuxfromscratch dot org>
+Date: 2018-12-26
+Initial Package Version: 20180414
+Upstream Status: Applied
+Origin: Upstream
+Description: Two fixes, cherry-picked from svn plus a CVE fix.
+I have removed the partial fixes for various system versions of poppler.
+
+r47469 Fix segfault in dvipdfm-x (XeTeX) on 1/2/4-bit transparent indexed PNGs.
+
+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."
