Update Information:

Upstream security update resolving an issue with `git clone --recurse-
submodules`.  From the [upstream release announcement](https://public-
inbox.org/git/[e-mail]/):  > These releases
fix a security flaw (CVE-2018-17456), which allowed an > attacker to execute
arbitrary code by crafting a malicious .gitmodules > file in a project cloned
with --recurse-submodules. > > When running "git clone
--recurse-submodules",
Git parses the supplied > .gitmodules file for a URL field and blindly passes it
as an argument > to a "git clone" subprocess.  If the URL field is set to a
string that > begins with a dash, this "git clone" subprocess interprets the
URL
as > an option.  This can lead to executing an arbitrary script shipped in > the
superproject as the user who ran "git clone". > > In addition to fixing
the
security issue for the user running "clone", > the 2.17.2, 2.18.1 and 2.19.1
releases have an "fsck" check which can > be used to detect such malicious
repository content when fetching or > accepting a push. See
"transfer.fsckObjects" in git-config(1). > > Credit for finding and fixing
this
vulnerability goes to joernchen > and Jeff King, respectively.
