EulerOS Virtualization 2.10.1 : openssh (EulerOS-SA-2022-1384)

high Nessus Plugin ID 159834

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

 - sshd in OpenSSH 6.2 through 8.x before 8.8, when certain non-default configurations are used, allows privilege escalation because supplemental groups are not initialized as expected. Helper programs for AuthorizedKeysCommand and AuthorizedPrincipalsCommand may run with privileges associated with group memberships of the sshd process, if the configuration specifies running the command as a different user.
 (CVE-2021-41617)

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.
