| Summary | A denial of service flaw was found in OpenSSL 0.9.8, 1.0.1, 1.0.2 through 1.0.2h, and 1.1.0 in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an excessive amount of CPU and fail to accept connections from other clients. |

| Title | OpenSSL におけるサービス運用妨害 (DoS) の脆弱性 |
|---|---|
| Summary | OpenSSL は、接続ハンドシェイク中に TLS/SSL プロトコルによる ALERT パケットの処理を適切に定義しないため、サービス運用妨害 (DoS) 状態にされる脆弱性が存在します。 |
| Possible impacts | リモートの攻撃者により、TLS/SSL サーバでの CPU の大量消費を引き起こされ、他のクライアントからの接続承認の失敗を引き起こされる可能性があります。 |
| Solution | ベンダより正式な対策が公開されています。ベンダ情報を参照して適切な対策を実施してください。 |
