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:

To determine the version of Sun Java System Application Server on a
system, the following command can be run:
$ <AS_INSTALL>/bin/asadmin version --verbose
Sun Java System Application Server 7 2004Q2UR3 (build A051525-273129)
(Where <AS_INSTALL> is the installation directory of the Application
Server).
To determine the version of Sun ONE Application Server on a system,
the following command can be run:
$ <WS-install>/https-<host>/start -version
(Where <WS-install> is top installation directory of Web Server and
<host> should be the actual host name on which the Web Server is
installed).
To determine the version of Sun Java System Proxy Server on a system,
the following command can be run:
$ <PS_INSTALL>/bin/ns-proxy -v
Sun ONE Web Proxy Server 3.6-SP9 B2006.191.1801 SP9
(Where <PS_INSTALL> is the installation directory of the Proxy
Server).
