A flaw was found in the bind9 package, where a malicious client may send many DNS messages over the TCP protocol, leading to instabilities on the server side and potentially causing a denial of service. The server will recover automatically once the attack ceases.
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
