Description
This security bulletin contains information about 1 security vulnerability.
1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2024-56433)
The vulnerability allows a remote user to escalate privileges on the system.
The vulnerability exists due to shadow-utils establishes a default /etc/subuid behavior (e.g., uid 100000 through 165535 for the first user account) that can realistically conflict with the uids of users defined on locally administered networks, potentially leading to account takeover by leveraging newuidmap for access to an NFS home directory (or same-host resources in the case of remote logins by these local network users).
Remediation
Install update from vendor's website.
