Astra Linux – Vulnerability in OVN

A flaw was discovered in the Open Virtual Network OVN. In OVN clusters where BFD is used between hypervisors for high availability, an attacker can inject specially crafted BFD packets from within unprivileged workloads, including virtual machines or containers, which can trigger a denial of...

Astra Linux – Vulnerability in OVN

A flaw was discovered in the Open Virtual Network OVN. Specially crafted UDP packets may bypass egress access control lists ACLs in OVN installations that are configured with a logical switch equipped with DNS records. This occurs if the same switch has any egress ACLs configured. This issue can...
