+Subject: Don't leak temporary file on failed ed-style patch
+
+Now that we write ed-style patches to a temporary file before we
+apply them, we need to ensure that the temporary file is removed
+before we leave, even on fatal error.
+
+* src/pch.c (do_ed_script): Use global TMPEDNAME instead of local
+ tmpname. Don't unlink the file directly, instead tag it for removal
+ at exit time.
+* src/patch.c (cleanup): Unlink TMPEDNAME at exit.
+
+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)")

+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:
