+ <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>
