1.修復(fù)的CVE ·CVE-2020-14339 描述：libvirt是一個(gè)用于實(shí)現(xiàn)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(tǒng)的一些虛擬產(chǎn)品。libvirt中存在安全漏洞。攻擊者可利用該漏洞繞過(guò)限制，提升權(quán)限。 ·CVE-2021-3975 描述：在 libvirt 中發(fā)現(xiàn)了一個(gè) use-after-free 缺陷。 qemuProcessHandleMonitorEOF 中的 qemuMonitorUnregister() 函數(shù)是使用多個(gè)線程調(diào)用的，而沒(méi)有受到監(jiān)視器鎖的充分保護(hù)。 當(dāng)guestos關(guān)閉時(shí)，virConnectGetAllDomainStats API 可能會(huì)觸發(fā)此漏洞。 具有只讀連接的非特權(quán)客戶端可以利用此漏洞通過(guò)導(dǎo)致 libvirt 守護(hù)進(jìn)程崩潰來(lái)執(zhí)行拒絕服務(wù)攻擊。 2.受影響的軟件包
