CVE-2002-0794 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:N/A:P

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.
