• Tcpdump 3.x - L2TP Parser Remote Denial of Service2003-12-20 · dos · linux · Verified

Impact

The L2TP protocol parser in tcpdump 3.8.1 and earlier allows remote attackers to cause a denial of service (infinite loop and memory consumption) via a packet with invalid data to UDP port 1701, which causes l2tp_avp_print to use a bad length value when calling print_octets.
