MinGit for Windows v2.21.0(4) Changes since MinGit v2.21.0(4) (August 17th 2019) Enhancements: * There is only one system gitconfig now (no more `C:\ProgramData\Git\config`), and it is in the top-level `etc` directory. * The Azure Pipeline was adjusted for changes in Homebrew and Cygwin that are outside of Git's control. Bug Fixes * CVE-2019-1348: 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-2019-1349: 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-2019-1350: Incorrect quoting of command-line arguments allowed remote code execution during a recursive clone in conjunction SSH URLs. * CVE-2019-1351: 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 assigned via subst <letter>: <path>. Git mistook such paths for relative paths, allowing writing outside of the worktree while cloning. * CVE-2019-1352: Git was unaware of NTFS Alternate Data Streams, allowing files inside the .git/ directory to be overwritten during a clone. * CVE-2019-1353: When running Git in WSL while accessing a working directory on a regular Windows drive, none of the NTFS protections were active. * CVE-2019-1354: 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-2019-1387: 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.
