+Git v2.14.5 Release Notes
+=========================
+
+This release is to address the recently reported CVE-2018-17456.
+
+Fixes since v2.14.4
+-------------------
+
+ * Submodules' "URL"s come from the untrusted .gitmodules file, but
+   we blindly gave it to "git clone" to clone submodules when "git
+   clone --recurse-submodules" was used to clone a project that has
+   such a submodule.  The code has been hardened to reject such
+   malformed URLs (e.g. one that begins with a dash).
+
+Credit for finding and fixing this vulnerability goes to joernchen
+and Jeff King, respectively.
