+  <title>International Components for Unicode: Multiple vulnerabilities</title>
+  <synopsis>
+    Two vulnerabilities have been discovered in the International Components
+    for Unicode, possibly resulting in the remote execution of arbitrary code
+    or a Denial of Service.

+    International Components for Unicode is a set of C/C++ and Java
+    libraries providing Unicode and Globalization support for software
+    applications.

+    Will Drewry (Google Security) reported a vulnerability in the regular
+    expression engine when using back references to capture \0 characters
+    (CVE-2007-4770). He also found that the backtracking stack size is not
+    limited, possibly allowing for a heap-based buffer overflow
+    (CVE-2007-4771).
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    A remote attacker could submit specially crafted regular expressions to
+    an application using the library, possibly resulting in the remote
+    execution of arbitrary code with the privileges of the user running the
+    application or a Denial of Service.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All International Components for Unicode users should upgrade to the
+    latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/icu-3.8.1-r1&quot;</code>
