The following package is affected: tcpdump CVE-2003-0989 tcpdump before 3.8.1 allows remote attackers to cause a denial of service (infinite loop) via certain ISAKMP packets, a different vulnerability than CVE-2004-0057. CVE-2003-1029 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. CVE-2004-0057 The rawprint function in the ISAKMP decoding routines (print-isakmp.c) for tcpdump 3.8.1 and earlier allows remote attackers to cause a denial of service (segmentation fault) via malformed ISAKMP packets that cause invalid 'len' or 'loc' values to be used in a loop, a different vulnerability than CVE-2003-0989.
