Medium

Base vector

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

Name of the Vulnerable Software and Affected Versions: FreeBSD versions 4 through 4.5

Description: The issue concerns the accept filter mechanism, which does not properly handle the removal of entries from the incomplete listen queue when a syncache is added. This allows remote attackers to cause a denial of service, affecting network service availability, by making a large number of connection attempts that fill the queue.

Recommendations: For FreeBSD versions 4 through 4.5, consider restricting access to the affected network services to minimize the risk of exploitation until a fix is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
