Serious PHP Vulnerability Prompts Multiple Websites in Japan to Suspend Services

After a serious security vulnerability in PHP, a scripting language widely used for website development, was disclosed on the 21st, the Japanese government on the 22nd called on website operators to take action. Multiple websites of Japanese central and local government agencies, railways, and financial institutions suspended services. PHP is a widely used server-side scripting language. It runs on servers, is used to generate web page content and interact with databases, and is also extensively integrated into other products. The security issue involves two vulnerabilities. Attackers may trigger a memory exhaustion state, causing memory corruption, and under specific conditions exploit the vulnerabilities to execute code remotely. On the 21st, the PHP development team released an emergency security update, and the vulnerabilities have been fixed. (Xinhua)
