1. 修復(fù)的CVE信息
CVE-2021-3631
描述：libvirt 在為 VM 的動(dòng)態(tài)標(biāo)簽生成 SELinux MCS 類別對(duì)時(shí)發(fā)現(xiàn)了一個(gè)漏洞。該漏洞允許一個(gè)被利用的訪客訪問(wèn)標(biāo)記為另一個(gè)訪客的文件，從而突破 sVirt 限制。此漏洞的最大威脅是機(jī)密性和完整性。
CVE-2021-3667
描述：在 libvirt 的 virStoragePoolLookupByTargetPath API 中存在不正確的鎖定漏洞。它是發(fā)生在 storagePoolLookupByTargetPath 函數(shù)中，其中鎖定的 virStoragePoolObj 對(duì)象在 ACL 權(quán)限失敗時(shí)未正確釋放。連接到具有有限 ACL 權(quán)限的讀寫套接字的客戶端可以使用此缺陷來(lái)獲取鎖并阻止其他用戶訪問(wèn)存儲(chǔ)池/卷 API,從而導(dǎo)致拒絕服務(wù)條件。此漏洞的最大威脅是系統(tǒng)可用性。
