+	<p>Integer Underflow Remote Code Execution Vulnerability</p>
+	<p>The specific flaw exists within the parsing of SPF macros.
+	When parsing SPF macros, the process does not properly
+	validate user-supplied data, which can result in an integer
+	underflow before writing to memory. An attacker can leverage
+	this vulnerability to execute code in the context of the
+	service account.</p>
