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
