Vulnerability Description
An issue was discovered in Xen through 4.14.x. Access rights of Xenstore nodes are per domid. Unfortunately, existing granted access rights are not removed when a domain is being destroyed. This means that a new domain created with the same domid will inherit the access rights to Xenstore nodes from the previous domain(s) with the same domid. Because all Xenstore entries of a guest below /local/domain/<domid> are being deleted by Xen tools when a guest is destroyed, only Xenstore entries of other guests still running are affected. For example, a newly created guest domain might be able to read sensitive information that had belonged to a previously existing guest domain. Both Xenstore implementations (C and Ocaml) are vulnerable.

Xen 安全漏洞
Vulnerability Description
Xen是英国剑桥（Cambridge）大学的一款开源的虚拟机监视器产品。该产品能够使不同和不兼容的操作系统运行在同一台计算机上，并支持在运行时进行迁移，保证正常运行并且避免宕机。 Xen through 4.14.x 版本存在安全漏洞，该漏洞源于Xenstore节点的访问权限是每个domid的。不幸的是，当域被破坏时，现有的被授予的访问权限不会被删除。这意味着，使用相同的domid创建的新域将从具有相同domid的前一个域继承对Xenstore节点的访问权限。
