2.17.5

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.
