+  <background>
+    <p>
+    JunkBuster is a filtering HTTP proxy, designed to enhance privacy and
+    remove unwanted content.

+  <description>
+    <p>
+    James Ranson reported a vulnerability when JunkBuster is configured to
+    run in single-threaded mode, an attacker can modify the referrer
+    setting by getting a victim to request a specially crafted URL
+    (CAN-2005-1108). Tavis Ormandy of the Gentoo Linux Security Audit Team
+    identified a heap corruption issue in the filtering of URLs
+    (CAN-2005-1109).

+  </description>
+  <impact type="high">
+    <p>
+    If JunkBuster has been configured to run in single-threaded mode, an
+    attacker can disable or modify the filtering of Referrer: HTTP headers,
+    potentially compromising the privacy of users. The heap corruption
+    vulnerability could crash or disrupt the operation of the proxy,
+    potentially executing arbitrary code.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All JunkBuster users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=net-proxy/junkbuster-2.0.2-r3&quot;</code>
