UnknownEPSS 9.92%

Last modified

CVE-2003-1029 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 9.92% chance of exploitation in the next 30 days.
