Fix and mitigation

WAF and other mitigations

Can a WAF block it? No. This is an integer overflow, usually triggered by an ordinary-looking number or size. Generic WAF rules do not recognise it; only a rule written for this specific CVE can.

Also consider: patch

Based on the weakness type only; no CVE-specific evidence yet. We check Cloudflare, AWS, Google Cloud Armor and Azure; for Akamai, Imperva, Fastly, F5, ask your vendor.
