Users can configure the desired ciphers using the “--cipher-suites” flag, and a default list of secure cipher suites is used if empty.\n\n### Workarounds\nBy default, no action is required. If users want to specify cipher suites using the '--cipher-suites' flag, they should try not to specify insecure cipher suites. Please refer to the [security documentation](https://etcd.io/docs/v3.4/op-guide/security/).\n\n### References\nFind out more on this vulnerability in the [security audit report](https://github.com/etcd-io/etcd/blob/main/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/main/security/security-release-process.md#product-security-committee-psc)\n\n## Affected packages\n\n- `go.etcd.io/etcd/client/pkg/v3 >= 3.4.0-rc.0, < 3.4.10`\n- `go.etcd.io/etcd/client/pkg/v3 < 3.3.23`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `go.etcd.io/etcd/client/pkg/v3 3.4.10`\n- `go.etcd.io/etcd/client/pkg/v3 3.3.23`","depth":"sunlit","depthScore":14,"depthScoreParts":{"impact":13.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
