+  <background>
+    <p>Vim is an efficient, highly configurable improved version of the classic
+      ‘vi’ text editor. gVim is the GUI version of Vim.
+    </p>
+  </background>
+  <description>
+    <p>
+      It was found that the <code>:source!</code> command was not restricted by
+      the sandbox mode. If modeline was explicitly enabled, opening a specially
+      crafted text file in vim could result in arbitrary command execution.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>A remote attacker could entice a user to open a specially crafted file
+      using Vim or gVim, possibly resulting in execution of arbitrary code with
+      the privileges of the process or a Denial of Service condition.
+    </p>
+  </impact>
+  <workaround>
+    <p>There is no known workaround at this time.</p>
+  </workaround>
+  <resolution>
+    <p>All Vim users should upgrade to the latest version:</p>
+    
+    <code>
+      # emerge --sync
+      # emerge --ask --oneshot --verbose "&gt;=app-editors/vim-8.1.1486"
