+	<h1>Problem Description:</h1>
+	<p>Insufficient validation of user-provided font parameters
+	can result in an integer overflow, leading to the use of
+	arbitrary kernel memory as glyph data. Characters that
+	reference this data can be displayed on the screen, effectively
+	disclosing kernel memory.</p>
+	<h1>Impact:</h1>
+	<p>Unprivileged users may be able to access privileged
+	kernel data.</p>
+	<p>Such memory might contain sensitive information, such
+	as portions of the file cache or terminal buffers. This
+	information might be directly useful, or it might be leveraged
+	to obtain elevated privileges in some way; for example, a
+	terminal buffer might include a user-entered password.</p>
