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
