Title: Sun Solaris admintool media installation path 
                        buffer overflow vulnerability 
Impact: Local attackers can gain root privileges 
Affected Technology: Sun Solaris 2.6,7,8 SPARC and x86 
Vendor Status: Vendor notified 
Discovered By: Kevin Kotas of the eSecurityOnline Research 
                        and Development Team

Advisory Location:

Description: 
Sun Solaris admintool is vulnerable to a buffer overflow condition 
that allows a local attacker to gain root privileges. The problem is 
due to insufficient bounds checking on the installation path. An 
attacker can create a path, supply it to admintool, and execute 
arbitrary code. 

Technical Recommendation: 
As a workaround solution, remove the setuid bit from the binary. 

chmod -s /usr/bin/admintool
