Three critical Remote Code Execution vulnerabilities have been reported in Memcached by security researcher Aleksandar Nikolich at Cisco Talos Group that expose major websites, including Facebook, Twitter, YouTube, Reddit, to hackers. The flaws could allow hackers to replace cached content with their malicious one in order to deface the website, serve phishing pages and malicious links to hijack victim’s machine. The company only took two days to build a patch on 31st October to fix the flaws.
