+
+The ATF libraries offer a simple API.  The API is orthogonal through the
+various bindings, allowing developers to quickly learn how to write test
+programs in different languages.
+
+ATF-based test programs offer a consistent end-user command-line interface to
+allow both humans and automation to run the tests.
+
+ATF-based test programs rely on an execution engine to be run and this
+execution engine is not shipped with ATF.  Kyua is the engine of choice.")

+Subject: [PATCH] Fix use after free in execute_with_shell.
+
+The temporary string returned by atf::env::get would be used outside
+its statement, which is invalid and cause undefined behavior.  Copy it
+to a local variable to avoid the issue.
+
+Fixes: https://github.com/freebsd/atf/issues/26
