+    <p>Two input validation errors have been discovered in how Zsh parses
+      scripts:
+    </p>
+    
+    <ul>
+      <li>Parsing a malformed shebang line could cause Zsh to call a program
+        listed in the second line (CVE-2018-0502)
+      </li>
+      <li>Shebang lines longer than 64 characters are truncated

+  <impact type="normal">
+    <p>An attacker could entice a user to execute a specially crafted script
+      using Zsh, possibly resulting in execution of arbitrary code with the
+      privileges of the process.

+  </impact>
+  <workaround>
+    <p>There is no known workaround at this time.</p>
+  </workaround>
+  <resolution>
+    <p>All Zsh users should upgrade to the latest version:</p>
