+  <title>libtasn1, GNU TLS: Security flaw in DER decoding</title>
+  <synopsis>
+    A flaw in the parsing of Distinguished Encoding Rules (DER) has been
+    discovered in libtasn1, potentially resulting in the execution of arbitrary
+    code.

+    Libtasn1 is a library used to parse ASN.1 (Abstract Syntax
+    Notation One) objects, and perform DER (Distinguished Encoding Rules)
+    decoding. Libtasn1 is included with the GNU TLS library, which is used
+    by applications to provide a cryptographically secure communications
+    channel.
+    </p>

+  <description>
+    <p>
+    Evgeny Legerov has reported a flaw in the DER decoding routines
+    provided by libtasn1, which could cause an out of bounds access to
+    occur.
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    A remote attacker could cause an application using libtasn1 to
+    crash and potentially execute arbitrary code by sending specially
+    crafted input.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All libtasn1 users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=dev-libs/libtasn1-0.2.18"</code>
