| 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). |
