+  <affected>
+    <package name="app-arch/gzip" auto="yes" arch="*">
+      <unaffected range="ge">1.3.3-r4</unaffected>

+  <background>
+    <p>
+    gzip (GNU zip) is popular compression program. The included gzexe
+    utility allows you to compress executables in place and have them
+    automatically uncompress and execute when you run them.
+    </p>
+  </background>
+  <description>
+    <p>
+    The script gzexe included with gzip contains a bug in the code that
+    handles tempfile creation. If the creation of a temp file fails when
+    using gzexe fails instead of bailing out it executes the command given
+    as argument.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    This could lead to priviege escalation by running commands under the
+    rights of the user running the self extracting file.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time. All users are encouraged to
+    upgrade to the latest available version.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All gzip users should upgrade to the latest stable version:
+    </p>
+    <code>
+    # emerge sync
+    
+    # emerge -pv "&gt;=app-arch/gzip-1.3.3-r4"
+    # emerge "&gt;=app-arch/gzip-1.3.3-r4"</code>
+    <p>
+    Additionally, once the upgrade is complete, all self extracting files
+    created with earlier versions gzexe should be recreated, since the
+    vulnerability is actually embedded in those executables.
+    </p>
