An issue exists where a configdrive can be used to trigger a denial of service. This occurs when the system processes a gzip bomb, which is a highly compressed archive that expands into an extremely large amount of uncompressed data upon extraction, exhausting system resources.

The issue concerns a vulnerability in image processing, where a crafted image could be used by an authenticated user to exploit undesired behaviors in qemu-img, potentially leading to unauthorized access to sensitive data.

A flaw was found in the Open Virtual Network (OVN) that allows specially crafted UDP packets to bypass egress access control lists (ACLs) in OVN installations configured with a logical switch with DNS records set on it and if the same switch has any egress ACLs configured. This issue can lead to unauthorized access to virtual machines and containers running on the OVN network. The OVN installation is vulnerable if a logical switch has DNS records set on it and if the same switch has any egress ACLs configured on it.
