Description
This security bulletin contains information about 1 security vulnerability.
1) Improper privilege management (CVE-ID: CVE-2024-48651)
The vulnerability allows a remote user to compromise the affected system.
The vulnerability exists due to improper privilege management when handling users without assigned supplementary groups. If the user has no groups assigned to their account, the server will assume the GID of 0 for this account. As a result, the user will gain access to files and directories owned by the system root user and will be able to modify them at will, leading to privilege escalation and system compromise.
Remediation
Install update from vendor's website.
