Microsoft today issued security updates for more than 100 newly-discovered vulnerabilities in its Windows operating system and related software, including four flaws that are already being exploited. In addition, Apple recently released emergency updates to quash a pair of zero-day bugs in iOS.

A client might overload the server by issue frequent RST frames. This can cause a massive amount of load on the remote system and so cause a DDOS attack. ### Impact This is a DDOS attack, any http2 server is affected and so you should update as soon as possible. ### Patches This is patched in version 4.1.100.Final. ### Workarounds A user can limit the amount of RST frames that are accepted per connection over a timeframe manually using either an own `Http2FrameListener` implementation or an `ChannelInboundHandler` implementation (depending which http2 API is used). ### References - https://www.cve.org/CVERecord?id=CVE-2023-44487 - https://blog.cloudflare.com/technical-breakdown-http2-rapid-reset-ddos-attack/ - https://cloud.google.com/blog/products/identity-security/google-cloud-mitigated-largest-ddos-attack-peaking-above-398-million-rps/

October's CVE update is here. Here's which security vulnerabilities to patch now to exorcise your Microsoft systems demons.

Ongoing Rapid Reset DDoS flood attacks exposed organizations need to patch CVE-2023-44487 immediately to head off crippling outages and business disruption.

DDoS for hire and live attacks hit both sides as cyber campaigns continue.

Amazon Web Services (AWS), Cloudflare, and Google on Tuesday said they took steps to mitigate record-breaking distributed denial-of-service (DDoS) attacks that relied on a novel technique called HTTP/2 Rapid Reset. The layer 7 attacks were detected in late August 2023, the companies said in a coordinated disclosure. The cumulative susceptibility to this attack is being tracked as CVE-2023-44487,

The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.

Summary Beginning in September 2023, Microsoft was notified by industry partners about a newly identified Distributed Denial-of-Service (DDoS) attack technique being used in the wild targeting HTTP/2 protocol. This vulnerability (CVE-2023-44487) impacts any internet exposed HTTP/2 endpoints. As an industry leader, Microsoft promptly opened an investigation and subsequently began working with industry partners for a coordinated disclosure and mitigation plan.
