NVD Vulnerability Detail

CVE-2015-0245

Summary	D-Bus 1.4.x through 1.6.x before 1.6.30, 1.8.x before 1.8.16, and 1.9.x before 1.9.10 does not validate the source of ActivationFailure signals, which allows local users to cause a denial of service (activation failure error returned) by leveraging a race condition involving sending an ActivationFailure signal before systemd responds.

D-Bus におけるサービス運用妨害 (DoS) の脆弱性

Title	D-Bus におけるサービス運用妨害 (DoS) の脆弱性
Summary	D-Bus は、ActivationFailure シグナルのソースを検証しないため、サービス運用妨害 (アクティベーション失敗のエラーリターン) 状態にされる脆弱性が存在します。
Possible impacts	ローカルユーザにより、systemd が応答する前の ActivationFailure シグナルの送信に伴う競合状態を利用されることで、サービス運用妨害 (アクティベーション失敗のエラーリターン) 状態に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。
