+Subject: Don't leak temporary file on failed multi-file ed-style patch
+
+The previous fix worked fine with single-file ed-style patches, but
+would still leak temporary files in the case of multi-file ed-style
+patch. Fix that case as well, and extend the test case to check for
+it.
+
+* src/patch.c (main): Unlink TMPEDNAME if needed before moving to
+  the next file in a patch.
+
+This closes bug #53820:
+https://savannah.gnu.org/bugs/index.php?53820
+
+Fixes: 123eaff0d5d1 ("Fix arbitrary command execution in ed-style patches (CVE-2018-1000156)")
+Fixes: 19599883ffb6 ("Don't leak temporary file on failed ed-style patch")
+
+Upstream-Status: Backport [http://git.savannah.gnu.org/cgit/patch.git/commit/?id=369dcccdfa6336e5a873d6d63705cfbe04c55727]
