Several vulnerabilities have been discovered in git, a fast, scalable, distributed revision control system. CVE-2019-1348 It was reported that the --export-marks option of git fast-import is exposed also via the in-stream command feature export-marks=..., allowing to overwrite arbitrary paths. CVE-2019-1387 It was discovered that submodule names are not validated strictly enough, allowing very targeted attacks via remote code execution when performing recursive clones. CVE-2019-19604 Joern Schneeweisz reported a vulnerability, where a recursive clone followed by a submodule update could execute code contained within the repository without the user explicitly having asked for that. It is now disallowed for `.gitmodules` to have entries that set `submodule.<name>.update=!command`. In addition this update addresses a number of security issues which are only an issue if git is operating on an NTFS filesystem .
