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:
