CVE-2016-7068 log
| Source |
|
| Severity | Medium |
| Remote | Yes |
| Type | Denial of service |
| Description | An issue has been found in PowerDNS allowing a remote, unauthenticated attacker to cause an abnormal CPU usage load on the PowerDNS server by sending crafted DNS queries, which might result in a partial denial of service if the system becomes overloaded. This issue is based on the fact that the PowerDNS server parses all records present in a query regardless of whether they are needed or even legitimate. A specially crafted query containing a large number of records can be used to take advantage of that behaviour. |
