+	<h1>Problem Description:</h1>
+	<p>System calls operating on file descriptors obtain a
+	reference to relevant struct file which due to a programming
+	error was not always put back, which in turn could be used
+	to overflow the counter of affected struct file.</p>
+	<h1>Impact:</h1>
+	<p>A local user can use this flaw to obtain access to files,
+	directories, sockets etc. opened by processes owned by other
+	users. If obtained struct file represents a directory from
+	outside of user's jail, it can be used to access files
+	outside of the jail. If the user in question is a jailed
+	root they can obtain root privileges on the host system.</p>
