  <description>
    <p>A vulnerability in Git causing Git-compatible clients that access
      case-insensitive or case-normalizing filesystems to overwrite the
      .git/config when cloning or checking out a repository, leading to
      execution of arbitrary commands.

  <impact type="normal">
    <p>An attacker can execute arbitrary commands on a client machine that
      clones a crafted malicious Git tree.
