Technical description

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).

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
