The origin disappeared, and the new revision does not include all the Poppler fixes. Adjust the package to take Arch's Poppler patches instead. * gnu/packages/patches/texlive-bin-CVE-2018-17407.patch: New file. * gnu/packages/patches/texlive-bin-pdftex-poppler-compat.patch, gnu/packages/patches/texlive-bin-xetex-poppler-compat.patch: Delete files. * gnu/local.mk (dist_patch_DATA): Adjust accordingly. * gnu/packages/tex.scm (texlive-bin)[source](patches): Likewise. [arguments]: Likewise.

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."
