    CVE-2002-1976

    Published: 31 Dec 2002Last Modified: 10 Apr 2026

    Summary:

    Details: ifconfig, when used on the Linux kernel 2.2 and later, does not report when the network interface is in promiscuous mode if it was put in promiscuous mode using PACKET_MR_PROMISC, which could allow attackers to sniff the network without detection, as demonstrated using libpcap.
