+Git v2.17.4 Release Notes
+=========================
+
+This release is to address the security issue: CVE-2020-5260
+
+Fixes since v2.17.3
+-------------------
+
+ * With a crafted URL that contains a newline in it, the credential
+   helper machinery can be fooled to give credential information for
+   a wrong host.  The attack has been made impossible by forbidding
+   a newline character in any value passed via the credential
+   protocol.
+
+Credit for finding the vulnerability goes to Felix Wilhelm of Google
+Project Zero.

+Git v2.17.5 Release Notes
+=========================
+
+This release is to address a security issue: CVE-2020-11008
+
+Fixes since v2.17.4
+-------------------
+
+ * With a crafted URL that contains a newline or empty host, or lacks
+   a scheme, the credential helper machinery can be fooled into
+   providing credential information that is not appropriate for the
+   protocol in use and host being contacted.
+
+   Unlike the vulnerability CVE-2020-5260 fixed in v2.17.4, the
+   credentials are not for a host of the attacker's choosing; instead,
+   they are for some unspecified host (based on how the configured
+   credential helper handles an absent "host" parameter).
+
+   The attack has been made impossible by refusing to work with
+   under-specified credential patterns.
+
+Credit for finding the vulnerability goes to Carlo Arenas.
