The --export-marks option of git fast-import is exposed also via the in-stream command feature export-marks=... and it allows overwriting arbitrary paths.(CVE-2019-1348)

When submodules are cloned recursively, under certain circumstances Git could be fooled into using the same Git directory twice. We now require the directory to be empty.(CVE-2019-1349)

Incorrect quoting of command-line arguments allowed remote code execution during a recursive clone in conjunction with SSH URLs.
(CVE-2019-1350)

While the only permitted drive letters for physical drives on Windows are letters of the US-English alphabet, this restriction does not apply to virtual drives . Git mistook such paths for relative paths, allowing writing outside of the worktree while cloning.
(CVE-2019-13510)

Git was unaware of NTFS Alternate Data Streams, allowing files inside the .git/ directory to be overwritten during a clone.(CVE-2019-1352)

When running Git in the Windows Subsystem for Linux (also known as 'WSL') while accessing a working directory on a regular Windows drive, none of the NTFS protections were active. (CVE-2019-1353)

Filenames on Linux/Unix can contain backslashes. On Windows, backslashes are directory separators. Git did not use to refuse to write out tracked files with such filenames.(CVE-2019-1354)

Recursive clones are currently affected by a vulnerability that is caused by too-lax validation of submodule names, allowing very targeted attacks via remote code execution in recursive clones.(CVE-2019-1387)
