+Subject: Fix arbitrary command execution in ed-style patches
+ (CVE-2018-1000156)
+
+* src/pch.c (do_ed_script): Write ed script to a temporary file instead
+of piping it to ed: this will cause ed to abort on invalid commands
+instead of rejecting them and carrying on.
+* tests/ed-style: New test case.
+* tests/Makefile.am (TESTS): Add test case.
+
+
+Without test to avoid automake due to @system package.
