+  <title>Hylafax: Insecure temporary file creation in xferfaxstats script</title>

+  <description>
+    <p>
+    Javier Fernandez-Sanguino has discovered that xferfaxstats cron script
+    supplied by Hylafax insecurely creates temporary files with predictable
+    filenames.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A local attacker could create symbolic links in the temporary file
+    directory, pointing to a valid file somewhere on the filesystem. When
+    the xferfaxstats script of Hylafax is executed, this would result in
+    the file being overwritten with the rights of the user running the
+    script, which typically is the root user.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Hylafax users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose net-misc/hylafax</code>
