medium Nessus Plugin ID 145734

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the openssh packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

 - The client side in OpenSSH 5.7 through 8.3 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client).(CVE-2020-14145)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
