Denial of Service Vulnerability in tcpdump's L2TP Protocol Parser

CVE-2003-1029 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:N/A:P

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.
