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.
