Package        : composer
Version        : 1.8.4-1+deb10u3
CVE ID         : CVE-2023-43655

Composer, an application-level dependency manager for the PHP
programming language was vulnerable.

CVE-2023-43655:

  Users publishing a composer.phar
  to a public web-accessible server where the composer.phar
  can be executed as a php file may be subject to a
  remote code execution vulnerability if PHP also has
  `register_argc_argv` enabled in php.ini

Moreover, a specific debian problem was fixed, and
autoload.php for composer imports depends
from /usr/share/php instead of trusting
path resolution.

For Debian 10 buster, this problem has been fixed in version
1.8.4-1+deb10u3.

We recommend that you upgrade your composer packages.

For the detailed security status of composer please refer to
its security tracker page at:
