1.  Bulletin Topics

    Sun advises of a potential compromise of 2 specific security certificates
    which had limited distribution. 

    Sun recommends that you follow the directions found at 
    http://sunsolve5.sun.com/secbull/certificate_howto.html
    to determine if your web browser has accepted any of the potentially 
    compromised certificates.

2.  Who is Affected
	
    A web browser that has accepted a Sun certificate with one the following 
    serial numbers:

    3181 B12D C422 5DAC A340 CF86 2710 ABE6 (Internet Explorer)
    17:05:FB:13:A2:2F:9A:F3:C1:30:F5:62:6E:12:50:4C (Netscape) 	

3.  Understanding the Vulnerability

    Web browsers accept security certificates from trusted sources.  A specific
    certificate from Sun may have received outside exposure.

    Systems that encounter this certificate are potentially vulnerable to attack
    from malicious applets, applications or components.


4.  Corrective Action

    Follow the instructions at 
    http://sunsolve5.sun.com/secbull/certificate_howto.html
    to determine if your browser has accepted one of the potentially compromised
    certificates.  If your browser contains this particular certificate, follow 
    the instructions to remove it.
