CVE-2004-0183
TCPDUMP 3.8.1 and earlier allows remote attackers to cause a denial of
service (crash) via ISAKMP packets containing a Delete payload with a
large number of SPI's, which causes an out-of-bounds read, as
demonstrated by the Striker ISAKMP Protocol Test Suite.

CVE-2004-0184
Integer underflow in the isakmp_id_print for TCPDUMP 3.8.1 and earlier
allows remote attackers to cause a denial of service (crash) via an
ISAKMP packet with an Identification payload with a length that
becomes less than 8 during byte order conversion, which causes an
out-of-bounds read, as demonstrated by the Striker ISAKMP Protocol
Test Suite.");
