CVE-2004-0184: Tcpdump

Medium severity, CVSS 5.0. EPSS: 60.3% chance of exploitation in the next 30 days.

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.

Affected products

• Tcpdump Tcpdump: up to and including 3.8.1
