What is CVE-2015-5694?

The vulnerability in OpenStack Designate allows for the failure to enforce the size limits for DNS record sets. This can lead to potential attacks where excessive data is transmitted, which may overwhelm servers and disrupt services relying on the DNS. By exploiting this vulnerability, an attacker could potentially manipulate DNS responses, leading to service degradation or denial of service. Proper validation of DNS record sizes is essential to maintain the integrity of network services.
