Amazon Linux 2023 Security Advisory: ALAS-2023-384
Advisory Release Date: 2023-10-12 16:11 Pacific
Advisory Updated Date: 2023-10-24 15:46 Pacific
Severity:
Medium
Issue Overview:
Composer is a dependency manager for PHP. 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. Versions 2.6.4, 2.2.22 and 1.10.27 patch this vulnerability. Users are advised to upgrade. Users unable to upgrade should make sure `register_argc_argv` is disabled in php.ini, and avoid publishing composer.phar to the web as this is not best practice. (CVE-2023-43655)
