1. Impact 
Buffer overflow vulnerabilities in the Sun Java System Web Proxy Server 
may allow a remote unprivileged user to crash either the Web Proxy Server 
or the Admin Server (of the Web Proxy Server) or execute arbitrary code 
with the privileges of the respective server processes. 

Note: The recommended UIDs for the Web Proxy Server and Admin Server are 
"nobody" and "root" respectively, at installation time. However, the 
administrator may have used different UIDs from the recommended ones 
during installation. 

Sun acknowledges with thanks, Matt Moore of Pentest Limited, for bringing 
these issues to our attention.

These issues can occur in the following release on all platforms: 

Sun Java System Web Proxy Server 3.6 Service Pack 4 and earlier

3. Symptoms 
There are no reliable symptoms that would indicate the 
described issues have been exploited to execute arbitrary code. The 
Web Proxy Server or Admin Server may crash if the buffer overflow 
vulnerabilities have been exploited.
