Sandbox escape due to incorrect boundary conditions in the Telemetry component. This vulnerability was fixed in Firefox 149, Firefox ESR 115.34, Firefox ESR 140.9, Thunderbird 149, and Thunderbird 140.9.
The following code is for security research and authorized testing only.
python
// Conceptual PoC for Telemetry Boundary Condition
// This is a simulation based on the vulnerability description
function triggerTelemetryOverflow() {
// Attempt to manipulate telemetry data structures
// to hit the incorrect boundary condition.
try {
// Hypothetical telemetry API interaction
// In a real scenario, this would involve specific memory layout
let maliciousPayload = new ArrayBuffer(0x1000);
let view = new DataView(maliciousPayload);
// Craft data designed to hit the boundary check failure
for (let i = 0; i < 0x1000; i++) {
view.setUint8(i, 0x41); // 'A'
}
// Trigger the vulnerability via the vulnerable component
// Note: Actual exploitation requires precise memory address knowledge
// and specific version targeting.
console.log("[+] Payload prepared for Telemetry component.");
// vulnerableTelemetryFunction(maliciousPayload);
} catch (e) {
console.log("[-] Exploit failed: " + e);
}
}
