+Git v2.14.6 Release Notes
+=========================
+
+This release addresses the security issues CVE-2019-1348,
+CVE-2019-1349, CVE-2019-1350, CVE-2019-1351, CVE-2019-1352,
+CVE-2019-1353, CVE-2019-1354, and CVE-2019-1387.
+
+Fixes since v2.14.5
+-------------------
+
+ * 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 with 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 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-2019-1354:
+ 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.
+
+Credit for finding these vulnerabilities goes to Microsoft Security
+Response Center, in particular to Nicolas Joly. The `fast-import`
+fixes were provided by Jeff King, the other fixes by Johannes
+Schindelin with help from Garima Singh.

+In conjunction with a vulnerability that was fixed in v2.20.2,
+`.gitmodules` is no longer allowed to contain entries of the form
+`submodule.<name>.update=!command`.
