+  <title>Mono: Buffer overflow</title>
+  <synopsis>
+    Mono's BigInteger implementation contains a buffer overflow vulnerability
+    that might lead to the execution of arbitrary code.

+    <package name="dev-lang/mono" auto="yes" arch="*">
+      <unaffected range="ge">1.2.5.1-r1</unaffected>

+  <background>

+    Mono provides the necessary software to develop and run .NET client and
+    server applications on various platforms.

+  <description>
+    <p>
+    IOActive discovered an error in the Mono.Math.BigInteger class, in the
+    reduction step of the Montgomery-based Pow methods, that could lead to
+    a buffer overflow.
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    A remote attacker could exploit this vulnerability by sending specially
+    crafted data to Mono applications using the BigInteger class, which
+    might lead to the execution of arbitrary code with the privileges of
+    the user running the application (possibly root) or a Denial of
+    Service.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Mono users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=dev-lang/mono-1.2.5.1-r1&quot;</code>
