Internet infrastructure provider Cloudflare fends off a massive 3.8 Tbps DDoS attack, surpassing the previous record. Learn how…

Cloudflare has disclosed that it mitigated a record-breaking distributed denial-of-service (DDoS) attack that peaked at 3.8 terabits per second (Tbps) and lasted 65 seconds. The web infrastructure and security company said it fended off "over one hundred hyper-volumetric L3/4 DDoS attacks throughout the month, with many exceeding 2 billion packets per second (Bpps) and 3 terabits per second (

Several of the flaws enable remote code execution and denial-of-service attacks while others enable data theft, session hijacking, and other malicious activity.

### Impact An abstract UNIX domain socket responsible for introspection is available without authentication locally to any user with access to the network namespace where the local juju agent is running. On a juju controller agent, denial of service can be performed by using the `/leases/revoke` endpoint. Revoking leases in juju can cause availability issues. On a juju machine agent that is hosting units, disabling the unit component can be performed using the `/units` endpoint with a "stop" action. ### Patches Patch: https://github.com/juju/juju/commit/43f0fc59790d220a457d4d305f484f62be556d3b Patched in: - 3.5.4 - 3.4.6 - 3.3.7 - 3.1.10 - 2.9.51 ### Workarounds No workaround. ### References https://github.com/juju/juju/blob/725800953aaa29dbeda4f806097bf838e61644dd/worker/introspection/worker.go#L125
