Category:	Denial of Service
Title:	PowerDNS Authoritative Server < 3.4.11 / 4.0 < 4.0.2 DoS Vulnerabilities
Summary:	An issue has been found in PowerDNS Authoritative Server allowing a remote,;unauthenticated attacker to cause a denial of service by opening a large number of TCP connections to the web;server. If the web server runs out of file descriptors, it triggers an exception and terminates the whole PowerDNS;process. While it's more complicated for an unauthorized attacker to make the web server run out of file;descriptors since its connection will be closed just after being accepted, it might still be possible.
