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. diff --git a/Documentation/RelNotes/2.15.4.txt b/Documentation/RelNotes/2.15.4.txt new file mode 100644 index 0000000000..dc241cba34 --- /dev/null +++ b/Documentation/RelNotes/2.15.4.txt @@ -0,0 +1,11 @@ +Git v2.15.4 Release Notes +========================= + +This release merges up the fixes that appear in v2.14.6 to address +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; see the release notes for that version for details. + +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`. diff --git a/Documentation/RelNotes/2.16.6.txt b/Documentation/RelNotes/2.16.6.txt new file mode 100644 index 0000000000..438306e60b --- /dev/null +++ b/Documentation/RelNotes/2.16.6.txt @@ -0,0 +1,8 @@ +Git v2.16.6 Release Notes +========================= + +This release merges up the fixes that appear in v2.14.6 and in +v2.15.4 addressing 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; see the release notes for those +versions for details. diff --git a/Documentation/RelNotes/2.17.3.txt b/Documentation/RelNotes/2.17.3.txt new file mode 100644 index 0000000000..5a46c94271 --- /dev/null +++ b/Documentation/RelNotes/2.17.3.txt @@ -0,0 +1,12 @@ +Git v2.17.3 Release Notes +========================= + +This release merges up the fixes that appear in v2.14.6 and in +v2.15.4 addressing 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; see the release notes for those +versions for details. + +In addition, `git fsck` was taught to identify `.gitmodules` entries +of the form `submodule.<name>.update=!command`, which have been +disallowed in v2.15.4. diff --git a/Documentation/git-fast-import.txt b/Documentation/git-fast-import.txt index e81117d27f..9e3b9581d7 100644 --- a/Documentation/git-fast-import.txt +++ b/Documentation/git-fast-import.txt @@ -50,6 +50,21 @@ OPTIONS memory used by fast-import during this run.
