-Subject: [PATCH] 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.
