CVE-2020-25637 説明 実行中の QEMU ドメインのネットワークインターフェース情報を要求する libvirt API（バージョン 6.8.0 より前）に、二重解放 double free の問題が発生しました。この脆弱性は、ポリシー制御ドライバー polkit に影響を与えます。具体的には、読み書きソケットに接続し、ACL 権限が制限されたクライアントが、この脆弱性を利用して libvirt デーモンをクラッシュさせ、サービス拒否 DoS...

A double free memory issue was found to occur in the libvirt API in versions before 6.8.0 responsible for requesting information about network interfaces of a running QEMU domain. This flaw affects the polkit access control driver. Specifically clients connecting to the read-write socket with limited ACL permissions could use this flaw to crash the libvirt daemon resulting in a denial of service or potentially escalate their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
