1. Impact

   Sun Java System Application Server, Sun Java System Proxy Server and
   Sun Java System Web Server are vulnerable to an RSA(1) Signature
   Verification vulnerability which may allow remote unprivileged users
   to construct certificates with forged signatures that go undetected
   and are accepted as valid.

   This issue is also described in the following documents:
