概要
リモートの Rocky Linux ホストにセキュリティ更新プログラムがありません。説明
リモートのRocky Linux 8ホストには、RLSA-2023:0099アドバイザリに記載された脆弱性の影響を受けるパッケージがインストールされています。- QEMU の QXL ディスプレイデバイスエミュレーションに領域外読み取りの欠陥が見つかりました。qxl_phys2virt() 関数は、ゲストの物理アドレスが指す構造体のサイズをチェックしません。このため、バースペースの末尾を超えて隣接するページが読み取られる可能性があります。悪意のあるゲストユーザーがこの欠陥を利用して、ホスト上の QEMU プロセスをクラッシュさせ、サービス拒否状態を引き起こす可能性があります。(CVE-2022-4144)
Nessus はこの問題をテストしておらず、代わりにアプリケーションの自己報告されたバージョン番号にのみ依存しています。
