5.0 MEDIUM — AV:N/AC:L/Au:N/C:N/I:N/A:P

Description

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.

Affected configurations

• lbl tcpdump 3.4 • lbl tcpdump 3.5 • lbl tcpdump 3.5.2 • lbl tcpdump 3.6.2 • lbl tcpdump 3.6.3 • lbl tcpdump 3.7
