+  <title>Opera: buffer overflows in 7.11 and 7.20</title>
+  <synopsis>
+    Buffer overflows exist in Opera 7.11 and 7.20 that can cause Opera to crash,
+    and can potentially overwrite arbitrary bytes on the heap leading to a
+    system compromise.

+    <p>
+    The Opera browser can cause a buffer allocated on the heap to overflow under
+    certain HREFs when rendering HTML.  The mail system is also deemed
+    vulnerable and an attacker can send an email containing a malformed HREF, or
+    plant the malicious HREF on a web site.

+  <impact type="high">
+    <p>
+    Certain HREFs can cause a buffer allocated on the heap to overflow when

+    which can result in a system compromise.

+  <resolution>
+    <p>
+    Users are encouraged to perform an 'emerge sync' and upgrade the package
+    to the latest available version.  Opera 7.22 is recommended as Opera 7.21 is
+    vulnerable to other security flaws. Specific steps to upgrade:
+    </p>
+    <code>
+    # emerge sync
+    # emerge -pv '&gt;=www-client/opera-7.22'
+    # emerge '&gt;=www-client/opera-7.22'
+    # emerge clean</code>
