漏洞描述

When a transaction is committed, C Xenstored will first check

the quota is correct before attempting to commit any nodes. It would

be possible that accounting is temporarily negative if a node has

been removed outside of the transaction.

Unfortunately, some versions of C Xenstored are assuming that the

quota cannot be negative and are using assert() to confirm it. This

will lead to C Xenstored crash when tools are built without -DNDEBUG

(this is the default).

解决建议

建议您更新当前系统或软件至最新版，完成漏洞的修复。
