1.修復的CVE ·CVE-2020-14339 描述：libvirt是一個用于實現Linux虛擬化功能的Linux API，它支持各種Hypervisor，包括Xen和KVM，以及QEMU和用于其他操作系統的一些虛擬產品。libvirt中存在安全漏洞。攻擊者可利用該漏洞繞過限制，提升權限。 ·CVE-2021-3975 描述：在 libvirt 中發現了一個 use-after-free 缺陷。 qemuProcessHandleMonitorEOF 中的 qemuMonitorUnregister() 函數是使用多個線程調用的，而沒有受到監視器鎖的充分保護。 當guestos關閉時，virConnectGetAllDomainStats API 可能會觸發此漏洞。 具有只讀連接的非特權客戶端可以利用此漏洞通過導致 libvirt 守護進程崩潰來執行拒絕服務攻擊。 2.受影響的軟件包
