CVE-2002-0666: Apple Mac OS X

Medium severity, CVSS 5.0. EPSS: 2.5% chance of exploitation in the next 30 days.

IPSEC implementations including (1) FreeS/WAN and (2) KAME do not properly calculate the length of authentication data, which allows remote attackers to cause a denial of service (kernel panic) via spoofed, short Encapsulating Security Payload (ESP) packets, which result in integer signedness errors.
