Security readout for executives and security teams
CVE-2019-3021 is a denial-of-service flaw in Oracle VM VirtualBox Core. A low-privileged local user with access to a system running affected VirtualBox versions could make VirtualBox hang or crash repeatedly, disrupting virtual machine use. The provided sources do not show data theft or code execution impact. Organizations running Oracle VM VirtualBox before 5.2.34 or 6.0.14 on systems where non-admin users can log in are in scope. Exposure is most likely on developer workstations, lab systems, build hosts, training environments, or shared virtualization machines. Treat this as a medium-priority availability risk. It is most urgent where VirtualBox supports critical development, testing, training, or operational workloads and untrusted or broad local user access exists. It should not outrank actively exploited remote code execution issues based on the supplied evidence. Mitigation focus: Upgrade VirtualBox to 5.2.34, 6.0.14, or a later supported fixed version.; Apply Oracle Critical Patch Update guidance for October 2019 where applicable.; Use Gentoo security advisories for Gentoo package remediation decisions..
