Description
This security bulletin contains information about 1 security vulnerability.
1) Improper Privilege Management (CVE-ID: CVE-2021-41617)
The vulnerability allows a local user to escalate privileges.
The vulnerability exists due to improper privilege management in sshd, when certain non-default configurations are used, 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. A local user can escalate privileges on the system.
Remediation
Install update from vendor's website.
