+  <title>PuTTY: Remote code execution</title>
+  <synopsis>
+    PuTTY was found to contain vulnerabilities that can allow a malicious SFTP
+    server to execute arbitrary code on unsuspecting PSCP and PSFTP clients.

+  <background>
+    <p>
+    PuTTY is a popular SSH client, PSCP is a secure copy
+    implementation, and PSFTP is a SSH File Transfer Protocol client.
+    </p>
+  </background>
+  <description>
+    <p>
+    Two vulnerabilities have been discovered in the PSCP and PSFTP
+    clients, which can be triggered by the SFTP server itself. These issues
+    are caused by the improper handling of the FXP_READDIR response, along
+    with other string fields.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    An attacker can setup a malicious SFTP server that would send
+    these malformed responses to a client, potentially allowing the
+    execution of arbitrary code on their system.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All PuTTY users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=net-misc/putty-0.57"</code>
