Description

A remote overflow exists in the Network Time Protocol Daemon (ntpd). The application fails to perform proper bounds checking resulting in a buffer overflow. With a specially crafted request, containing an overly long 'readvar' argument a remote attacker can gain access to root privileges resulting in a loss of integrity.
