Summary
Out-of-bounds read in DNS Server allows an authorized attacker to disclose information over a network. The attacker can read data outside the intended memory bounds.
Risk Assessment
An authorized attacker can disclose confidential information transmitted over the network, potentially leading to data leakage. Organizations using the DNS Server are exposed to confidentiality breaches.
Recommendation
Update the DNS Server to the latest patched version. Restrict access to the DNS service to trusted users only.
