Sun(sm) Alert Notification
* Sun Alert ID: 102657
* Synopsis: Security Vulnerability With RSA Signature Affects the
Sun Secure Global Desktop Software
* Category: Security
* Product: Sun Secure Global Desktop Software 4.2
* BugIDs: 6469123
* Avoidance: Upgrade
* State: Resolved
* Date Released: 06-Oct-2006, 07-Dec-2006

1. Impact
Sun Secure Global Desktop (SSGD) software 4.2 is impacted by an RSA
signature forgery vulnerability. This vulnerability may allow an
untrusted server to present a forged identity to clients connecting to
that server when secure connections are in use.
This vulnerability may also affect SSGD servers which are configured
to use web server authentication and client certificates. Under these
circumstances, it may be possible for a local or remote unprivileged
user to forge a valid identity and log in to an SSGD server, allowing
unauthorized access to the applications available for that identity.
This issue is also described in the following documents:
