Fedora 41: Security Advisory FEDORA-2025-da047483d8 critical: PHP issues

fedora
Calendar Grey July 13, 2025
Dist Fedora Esm H88
Upgrading to PHP 8.3.23 on Fedora 41 fixes memory leaks and effectively tackles significant concerns.
PHP version 8.3.23 (03 Jul 2025) Core: Fixed GH-18695 (zend_ast_export() - float number is not preserved)

Summary

PHP is an HTML-embedded scripting language. PHP attempts to make it

easy for developers to write dynamically generated web pages. PHP also

offers built-in database integration for several commercial and

non-commercial database management systems, so writing a

database-enabled webpage with PHP is fairly simple. The most common

use of PHP coding is probably as a replacement for CGI scripts.
