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.
