However, it is possible to include the gateway address as an endpoint. This results in a denial of service, since the endpoint can become stuck in a loop of requesting itself until there are no more available file descriptors to accept connections on the gateway.\n\n### References\nFind out more on this vulnerability in the [security audit report](https://github.com/etcd-io/etcd/blob/master/security/SECURITY_AUDIT.pdf)\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Contact the [etcd security committee](https://github.com/etcd-io/etcd/blob/master/security/security-release-process.md#product-security-committee-psc)\n\n## Affected packages\n\n- `go.etcd.io/etcd >= 3.4.0-rc.0, < 3.4.10`\n- `go.etcd.io/etcd < 3.3.23`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `go.etcd.io/etcd 3.4.10`\n- `go.etcd.io/etcd 3.3.23`","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.4,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
