+
+    x509: excessive resource use verifying policy constraints
+    
+    A security vulnerability has been identified in all supported versions
+    of OpenSSL related to the verification of X.509 certificate chains
+    that include policy constraints.  Attackers may be able to exploit this
+    vulnerability by creating a malicious certificate chain that triggers
+    exponential use of computational resources, leading to a denial-of-service
+    (DoS) attack on affected systems.
+    
+    Fixes CVE-2023-0464
