    It was discovered that there were a number of command-line injection
    vulnerabilities in Composer, a popular dependency manager for PHP.

    The 'install', 'status', 'reinstall' and 'remove' functionality had
    issues when used with Git or Hg repositories which used maliciously-
    crafted branch names, which could have been abused to execute
    arbitrary shell commands.

    For Debian 10 buster, this problem has been fixed in version
    1.8.4-1+deb10u4.

    We recommend that you upgrade your composer packages.

    For the detailed security status of composer please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/composer
