Git v2.30.6 Release Notes

This release addresses the security issues CVE-2022-39253 and CVE-2022-39260.

• CVE-2022-39253:

     When relying on the `--local` clone optimization, Git dereferences
     symbolic links in the source repository before creating hardlinks
     (or copies) of the dereferenced link in the destination repository.
     This can lead to surprising behavior where arbitrary files are
     present in a repository's `$GIT_DIR` when cloning from a malicious
     repository.
  
     Git will no longer dereference symbolic links via the `--local`
     clone mechanism, and will instead refuse to clone repositories that
     have symbolic links present in the `$GIT_DIR/objects` directory.
  
     Additionally, the value of `protocol.file.allow` is changed to be
     "user" by default.
  

• CVE-2022-39260:

     An overly-long command string given to `git shell` can result in
     overflow in `split_cmdline()`, leading to arbitrary heap writes and
     remote code execution when `git shell` is exposed and the directory
     `$HOME/git-shell-commands` exists.
  
     `git shell` is taught to refuse interactive commands that are
     longer than 4MiB in size. `split_cmdline()` is hardened to reject
     inputs larger than 2GiB.
