+  <title>mit-krb5: Multiple buffer overflows in krb5_aname_to_localname</title>
+  <synopsis>
+    mit-krb5 contains multiple buffer overflows in the function
+    krb5_aname_to_localname(). This could potentially lead to a complete remote
+    system compromise.

+    mit-krb5 is the free implementation of the Kerberos network authentication

+  <description>
+    <p>
+    The library function krb5_aname_to_localname() contains multiple buffer
+    overflows. This is only exploitable if explicit mapping or rules-based
+    mapping is enabled. These are not enabled as default.
+    </p>
+    <p>
+    With explicit mapping enabled, an attacker must authenticate using a
+    principal name listed in the explicit mapping list.
+    </p>
+    <p>
+    With rules-based mapping enabled, an attacker must first be able to create
+    arbitrary principal names either in the local realm Kerberos realm or in a
+    remote realm from which the local realm's service are reachable by
+    cross-realm authentication.
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    An attacker could use these vulnerabilities to execute arbitrary code with
+    the permissions of the user running mit-krb5, which could be the root user.
+    </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>
+    mit-krb5 users should upgrade to the latest version:
