Descriptions
By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources.
Al falsificar el resolver objetivo con respuestas que presentan una firma EdDSA malformada, un atacante puede desencadenar una pequeña pérdida de memoria. Es posible erosionar gradualmente la memoria disponible hasta el punto de que named sea bloqueado por falta de recursos
A flaw was found in the Bind package, where the DNSSEC verification code for the EdDSA algorithm leaks memory when there is a signature length mismatch. By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak, resulting in crashing the program.
