+	  <p>CVE-2013-4576 has been assigned to this security bug.</p>
+
+	  <p>The paper describes two attacks.  The first attack allows
+to distinguish keys: An attacker is able to notice which key is
+currently used for decryption.  This is in general not a problem but
+may be used to reveal the information that a message, encrypted to a
+commonly not used key, has been received by the targeted machine.  We
+do not have a software solution to mitigate this attack.</p>
+
+	  <p>The second attack is more serious.  It is an adaptive
+chosen ciphertext attack to reveal the private key.  A possible
+scenario is that the attacker places a sensor (for example a standard
+smartphone) in the vicinity of the targeted machine.  That machine is
+assumed to do unattended RSA decryption of received mails, for example
+by using a mail client which speeds up browsing by opportunistically
+decrypting mails expected to be read soon.  While listening to the
+acoustic emanations of the targeted machine, the smartphone will send
+new encrypted messages to that machine and re-construct the private
+key bit by bit.  A 4096 bit RSA key used on a laptop can be revealed
+within an hour.</p>
