Test ID:1.3.6.1.4.1.25623.1.0.103939
Category:Denial of Service
Title:OpenSSH Denial of Service Vulnerability
Summary:OpenSSH is prone to a remote denial-of-service vulnerability.
Description:Summary:
OpenSSH is prone to a remote denial-of-service vulnerability.

Vulnerability Insight:
The default configuration of OpenSSH through 6.1 enforces a fixed
time limit between establishing a TCP connection and completing a login, which makes it easier for
remote attackers to cause a denial of service (connection-slot exhaustion) by periodically making
many new TCP connections.

Vulnerability Impact:
Exploiting this issue allows remote attackers to trigger denial-of-
service conditions.

Affected Software/OS:
OpenSSH 6.1 and prior.

Solution:
Updates are available. Please see the references for more information.

CVSS Score:
5.0
