Three months ago, we announced Octane’s first CVE for a heap information disclosure vulnerability in Chromium. VirtualBox is the world’s most popular open-source, cross-platform virtualization product. It is used for software development, testing, cloud deployment, legacy application support and secure remote work.IBM, Google, Uber, Airbnb, and many other public companies use VirtualBox, while the software also plays a key role in multiple specialist security products.
