Last modified

CVE-2010-5107 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 16.51% chance of exploitation in the next 30 days.
