A researcher has disclosed the details of a zero-day vulnerability affecting Oracle’s VirtualBox virtualization software. The flaw appears serious as exploitation can allow a guest-to-host escape.
Russian researcher Sergey Zelenyuk discovered the security hole and he decided to make his findings public before giving Oracle the chance to release a patch due to his “disagreement with [the] contemporary state of infosec, especially of security research and bug bounty.” According to Zelenyuk, the vulnerability affects VirtualBox 5.2.20 and prior versions – 5.2.20 is the latest version – and it can be exploited on any host or guest operating system as the underlying bugs affect shared code.
