N/A
Vulnerability Description
An issue was discovered in Xen through 4.14.x. Some OSes (such as Linux, FreeBSD, and NetBSD) are processing watch events using a single thread. If the events are received faster than the thread is able to handle, they will get queued. As the queue is unbounded, a guest may be able to trigger an OOM in the backend. All systems with a FreeBSD, Linux, or NetBSD (any version) dom0 are vulnerable.

Xen 缓冲区错误漏洞
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 4.14.x版本及之前版本存在安全漏洞，该漏洞源于正在使用单个线程处理监视事件。如果接收事件的速度快于线程处理的速度，那么它们将进入队列。由于队列是无限制的，客户端可能会在后端触发一个OOM。所有带有FreeBSD、Linux或NetBSD(任何版本)dom0的系统都是脆弱的。
