CVE-2002-0574 is a vulnerability of currently unknown severity. Memory leak in FreeBSD 4.5 and earlier allows remote attackers to cause a denial of service (memory exhaustion) via ICMP echo packets that trigger a bug in ip_output() in which the reference count for a routing table entry is not decremented, which prevents the entry from being removed.. EPSS estimates a 1.96% chance of exploitation in the next 30 days.
