CVE-2023-34323 (published 2024-01-05T16:30:32.305Z)
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).
