World leaders warn against security flaw found in PHP computer programming

Authorities in Europe, Asia and other continents have temporarily taken some government websites offline to protect against newly discovered security vulnerabilities in a programming language used to power the vast majority of sites on the internet. On Wednesday, the vulnerabilities in the PHP programming language prompted a rare public warning from the United States National Security Agency (NSA), which advised websites be taken offline if they could not immediately be updated. “Effective Immediately, all organizations using PHP for their systems are advised to be prepared for an update addressing two critical vulnerabilities,” the NSA said in a social media post.
