Description

This security bulletin contains information about 1 security vulnerability.


1) Security features bypass (CVE-ID: CVE-2025-0650)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to improper handling of UDP packets. A remote attacker can send specially crafted UDP packets that bypass egress access control lists (ACLs) in OVN installations and gain unauthorized access to virtual machines and containers running on the OVN network.

Successful exploitation of the vulnerability requires that ACLs on OVN installations are configured with a logical switch with DNS records set on it and if the same switch has any egress ACLs configured.


Remediation

Install update from vendor's website.
