Authenticated denial of service via heap buffer overflow
Published Aug 14, 2024 · Updated Aug 16, 2024
Heap buffer overflow in affected Zoom Workplace clients and SDKs allows remote authenticated users to interrupt service over a network. Zoom identifies heap-resident memory as the overwritten locus but has not published the responsible component, operation, or triggering input. A valid Zoom session is required; exploitation affects availability by interrupting the vulnerable app, SDK host, room client, or controller.
