CVE-2002-0794

FreeBSD 4-4.5 - Denial of Service via Accept Filter Queue Overflow

Title source: llm
STIX 2.1

Description

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.
