Vulnerability in Freebsd

CVE-2002-0794

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: 0.016 (73.8th percentile) — read the EPSS interpretation.
