  It was found that ELinks performed client credentials delegation during the
  client-to-server GSS security mechanisms negotiation. A rogue server could
  use this flaw to obtain the client's credentials and impersonate that
  client to other servers that are using GSSAPI. (CVE-2012-4545)

  This issue was discovered by Marko Myllynen of Red Hat.

  All ELinks users are advised to upgrade to this updated package, which
  contains a backported patch to resolve the issue.");
