+Subject: [PATCH] Fix swapping fake lines in pch_swap
+
+* src/pch.c (pch_swap): Fix swapping p_bfake and p_efake when there is a
+blank line in the middle of a context-diff hunk: that empty line stays
+in the middle of the hunk and isn't swapped.
+
+Fixes: https://savannah.gnu.org/bugs/index.php?53133
+Signed-off-by: Andreas Gruenbacher <agruen@gnu.org>
+
+Upstream-Status: Backport [https://git.savannah.gnu.org/git/patch.git]
+CVE: CVE-2018-6952
