+  <title>Rootkit Hunter: Insecure temporary file creation</title>
+  <synopsis>
+    Rootkit Hunter is vulnerable to symlink attacks, potentially allowing a
+    local user to overwrite arbitrary files.

+    <p>
+    Rootkit Hunter is a scanning tool to detect rootkits, backdoors
+    and local exploits on a local machine. Rootkit Hunter uses downloaded
+    data files to check file integrity. These files are updated via the
+    check_update.sh script.

+  <description>
+    <p>
+    Sune Kloppenborg Jeppesen and Tavis Ormandy of the Gentoo Linux
+    Security Team have reported that the check_update.sh script and the
+    main rkhunter script insecurely creates several temporary files with
+    predictable filenames.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A local attacker could create symbolic links in the temporary
+    files directory, pointing to a valid file somewhere on the filesystem.
+    When rkhunter or the check_update.sh script runs, this would result in
+    the file being overwritten with the rights of the user running the
+    utility, which could be the root user.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Rootkit Hunter users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=app-forensics/rkhunter-1.2.3-r1"</code>
