Linux UDP packets allows remote attacker to fingerprint operating system
|linux-udp-fingerprint (8588)||Low Risk|
The UDP implementation in Linux kernel could allow a remote attacker to identify the operating system being used. UDP packets in Linux kernel versions 2.4.x are transmitted with a constant IP Identification field set to 0.
