EulerOS 2.0 SP10 : openssh (EulerOS-SA-2022-2167)

low Nessus Plugin ID 163569

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - ** DISPUTED ** An issue was discovered in OpenSSH before 8.9. If a client is using public-key authentication with agent forwarding but without -oLogLevel=verbose, and an attacker has silently modified the server to support the None authentication option, then the user cannot determine whether FIDO authentication is going to confirm that the user wishes to connect to that server, or that the user wishes to allow that server to connect to a different server on the user's behalf. NOTE: the vendor's position is 'this is not an authentication bypass, since nothing is being bypassed.' (CVE-2021-36368)

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.

Solution

Update the affected openssh packages.
