Git for Windows v2.40.0

Changes since Git for Windows v2.39.2 (February 14th 2023)

As announced previously, Git for Windows will drop support for Windows
7 and for Windows 8 in one of the next versions, following Cygwin's and
MSYS2's lead (Git for Windows relies on MSYS2 for components such as
Bash and Perl).

Also following the footsteps of the MSYS2 and Cygwin projects on which
Git for Windows depends, the 32-bit variant of Git for Windows is
nearing its end of support.

New Features

  * Comes with Git v2.40.0.
  * In the olden Git days, there were "dashed" Git commands (e.g.
    git-commit instead of git commit). These haven't been supported for
    interactive use in a really, really long time. But they still
    worked in Git aliases and hooks ("scripts"). Since Git v1.5.4
    (released on February 2nd, 2008), it was discouraged/deprecated to
    use dashed Git commands even in scripts. As of this version, Git
    for Windows no longer supports these dashed commands.
  * Comes with tig v2.5.8.
  * Comes with Bash v5.2 patchlevel 15.
  * Comes with OpenSSL v1.1.1t.
  * Comes with GNU TLS v3.8.0.
  * Comes with cURL v7.88.1.
  * Comes with libfido2 v1.13.0.
  * Comes with Git Credential Manager v2.0.935.

Bug Fixes

  * Some commands mishandled absolute paths near the drive root (e.g.
    scalar unregister C:/foo), which has been fixed.
  * When trying to call Cygwin (or for that matter, MSYS2) programs
    from Git Bash, users would frequently be greeted with cryptic error
    messages about a "cygheap" or even just an even more puzzling exit
    code 127. Many of these calls now succeed, allowing basic
    interactions. While it is still not possible for, say, Cygwin's
    vim.exe to interact with the Git Bash's terminal window, it is now
    possible for Cygwin's zstd.exe in conjuction with Git for Windows'
    tar.exe to handle .tar.zst archives.

MinGit for Windows v2.35.7

Changes since Git for Windows v2.35.6 (January 17 2023):

Bug Fixes

* CVE-2023-22490:

  Using a specially-crafted repository, Git can be tricked into using
  its local clone optimization even when using a non-local transport.
  Though Git will abort local clones whose source $GIT_DIR/objects
  directory contains symbolic links (c.f., CVE-2022-39253), the objects
  directory itself may still be a symbolic link.

  These two may be combined to include arbitrary files based on known
  paths on the victim's filesystem within the malicious repository's
  working copy, allowing for data exfiltration in a similar manner as
  CVE-2022-39253.

* CVE-2023-23946:

  By feeding a crafted input to "git apply", a path outside the
  working tree can be overwritten as the user who is running "git
  apply".

* A mismatched type in `attr.c::read_attr_from_index()` which could
  cause Git to errantly reject attributes on Windows and 32-bit Linux
  has been corrected.

MinGit for Windows v2.35.6

Changes since Git for Windows v2.35.5 (October 13 2022):

Bug Fixes

* CVE-2022-41903:

   git log has the ability to display commits using an arbitrary
   format with its --format specifiers. This functionality is also
   exposed to git archive via the export-subst gitattribute.

   When processing the padding operators (e.g., %<(, %<|(, %>(,
   %>>(, or %><( ), an integer overflow can occur in
   pretty.c::format_and_pad_commit() where a size_t is improperly
   stored as an int, and then added as an offset to a subsequent
   memcpy() call.

   This overflow can be triggered directly by a user running a
   command which invokes the commit formatting machinery (e.g., git
   log --format=...). It may also be triggered indirectly through
   git archive via the export-subst mechanism, which expands format
   specifiers inside of files within the repository during a git
   archive.

   This integer overflow can result in arbitrary heap writes, which
   may result in remote code execution.

* CVE-2022-23521:

   gitattributes are a mechanism to allow defining attributes for
   paths. These attributes can be defined by adding a `.gitattributes`
   file to the repository, which contains a set of file patterns and
   the attributes that should be set for paths matching this pattern.

   When parsing gitattributes, multiple integer overflows can occur
   when there is a huge number of path patterns, a huge number of
   attributes for a single pattern, or when the declared attribute
   names are huge.

   These overflows can be triggered via a crafted `.gitattributes` file
   that may be part of the commit history. Git silently splits lines
   longer than 2KB when parsing gitattributes from a file, but not when
   parsing them from the index. Consequentially, the failure mode
   depends on whether the file exists in the working tree, the index or
   both.

   This integer overflow can result in arbitrary heap reads and writes,
   which may result in remote code execution.
