Summary: Cloudflare GoFlow vulnerable to a Denial of Service in the sflow packet handling package
Details: ### Impact The sflow decode package prior to version 3.4.4 does not employ sufficient packet sanitisation which can lead to a denial of service attack. Attackers can craft malformed packets causing the process to consume huge amounts of memory resulting in a denial of service. ### Specific Go Packages Affected github.com/cloudflare/goflow/v3/decoders/sflow ### Patches Version 3.4.4 contains patches fixing this. ### Workarounds A possible workaround is to not have your goflow collector publicly reachable. ### For more information If you have any questions or comments about this advisory: * Open an issue in [goflow repo](https://github.com/cloudflare/goflow) * Email us [netdev[@]cloudflare.com ](mailto:[email protected])
