CVE-2002-0794: Freebsd

Medium severity, CVSS 5.0. EPSS: 1.6% chance of exploitation in the next 30 days.

The accept_filter mechanism in FreeBSD 4 through 4.5 does not properly remove entries from the incomplete listen queue when adding a syncache, which allows remote attackers to cause a denial of service (network service availability) via a large number of connection attempts, which fills the queue.
