CVE-2002-0794 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.63% chance of exploitation in the next 30 days.
