Update Information:

Security fix for CVE-2020-5260 and CVE-2020-11008 CVE-2020-5260 – From the
upstream [release
notes](https://www.kernel.org/pub/software/scm/git/docs/RelNotes/2.17.4.txt): >
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. CVE-2020-11008 – From the upstream
[release
notes](https://www.kernel.org/pub/software/scm/git/docs/RelNotes/2.17.5.txt):
> 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.
