  10 The change to disallow `submodule.<name>.update=!command` entries in
  11 `.gitmodules` which was introduced v2.15.4 (and for which v2.17.3
  12 added explicit fsck checks) fixes the vulnerability in v2.20.x where a
  13 recursive clone followed by a submodule update could execute code
  14 contained within the repository without the user explicitly having
  15 asked for that (CVE-2019-19604).
