Zoom disclosed a second buffer overflow in Windows builds prior to 6.4.5, including VDI and Room components, which also results in denial of service. The flaw reinforces the importance of patching all instances, not just client endpoints.
Zoom emphasizes the importance of immediate patching:
“Users can help keep themselves secure by applying the latest updates available at https://zoom.us/download,” the advisory urges repeatedly.
For both IT admins managing cross-platform environments and remote users, keeping your Zoom client updated is crucial for protection against exploitation.
