Descriptions

Hyperledger Fabric 2.3 allows attackers to cause a denial of service (orderer crash) by repeatedly sending a crafted channel tx with the same Channel name. NOTE: the official Fabric with Raft prevents exploitation via a locking mechanism and a check for names that already exist.

Hyperledger Fabric 2.3 permite a los atacantes provocar una denegación de servicio (caída del pedido) enviando repetidamente un tx de canal diseñado con el mismo nombre de canal. NOTA: el Fabric with Raft oficial evita la explotación mediante un mecanismo de bloqueo y una verificación de nombres que ya existen.
