          "text": "Es existiert eine Schwachstelle in GNU libc in der DNS Resolver-Funktion \"getaddrinfo\". Bei der Verarbeitung von DNS Anfragen des Typs \"AF_UNSPEC\" kann ein Stack-basierter Puffer\u00fcberlauf entstehen und dadurch beliebiger Code zur Ausf\u00fchrung kommen. Diese DNS Anfragen kommen beispielsweise bei paralleler Nutzung von IPv4 und IPv6 vor. Ein Angreifer, der einen DNS Server kontrolliert, kann durch speziell gestaltete DNS Antworten beliebigen Code auf dem betroffenen System zur Ausf\u00fchrung bringen. Zur erfolgreichen Ausnutzung dieser Schwachstelle muss der Angreifer den Benutzer dazu bringen eine Netzwerkverbindung zu \u00f6ffnen, die einem manipulierten DNS Server verwendet."
