+  <title>Shorewall : Insecure temp file handling</title>
+  <synopsis>
+    Shorewall contains a bug in the code handling the creation of temporary
+    files and directories. This can allow a non-root user to overwrite
+    arbitrary system files.
+  </synopsis>

+  <affected>
+    <package name="net-firewall/shorewall" auto="yes" arch="*">
+      <unaffected range="ge">1.4.10f</unaffected>
+      <vulnerable range="le">1.4.10c</vulnerable>
+    </package>
+  </affected>
+  <background>
+    <p>
+    Shorewall is a high level tool for configuring Netfilter, the firewall
+    facility included in the Linux Kernel.
+    </p>
+  </background>
+  <description>
+    <p>
+    Shorewall uses temporary files and directories in an insecure manner. A
+    local user could create symbolic links at specific locations,
+    eventually overwriting other files on the filesystem with the rights of
+    the shorewall process.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    An attacker could exploit this vulnerability to overwrite arbitrary
+    system files with root privileges, resulting in Denial of Service or
+    further exploitation.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time. All users should upgrade to
+    the latest available version of Shorewall.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All users should upgrade to the latest available version of Shorewall,
+    as follows:
+    </p>
+    <code>
+    # emerge sync
+    
+    # emerge -pv "&gt;=net-firewall/shorewall-1.4.10f"
+    # emerge "&gt;=net-firewall/shorewall-1.4.10f"</code>
