      <title>CVE-2023-34323 — xenstored: A transaction conflict can crash C Xenstored</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2023-34323</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Xen&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;
&lt;p&gt;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).&lt;/p&gt;</description>
