1. Impact 
A buffer overflow vulnerability exists in the Netscape Network Security 
Services (NSS) library suite that is a security component used by most of the 
Sun Java Enterprise System (JES) components such as Web Server, App Server and 
Portal Server. This vulnerability may allow a remote unprivileged user to 
execute arbitrary code on vulnerable systems during SSLv2 connection 
negotiation. This issue is described in the Internet Security Systems Advisory 
at http://xforce.iss.net/xforce/alerts/id/180. 

Additional information about JES 2004Q2 can be found at
