+	<p>A vulnerability was discovered in the PyYAML library
+	in versions before 5.4, where it is susceptible to arbitrary
+	code execution when it processes untrusted YAML files
+	through the full_load method or with the FullLoader loader.
+	Applications that use the library to process untrusted
+	input may be vulnerable to this flaw. This flaw allows
+	an attacker to execute arbitrary code on the system by
+	abusing the python/object/new constructor. This flaw is
+	due to an incomplete fix for CVE-2020-1747.</p>
