Descriptions

A flaw was found in openCryptoki. The openCryptoki Soft token does not check if an EC key is valid when an EC key is created via C_CreateObject, nor when C_DeriveKey is used with ECDH public data. This may allow a malicious user to extract the private key by performing an invalid curve attack.

Se ha encontrado un fallo en openCryptoki. El token de openCryptoki Soft no comprueba si una clave EC es válida cuando es creada una clave EC por medio de C_CreateObject, ni cuando es usada C_DeriveKey con datos públicos ECDH. Esto puede permitir a un usuario malicioso extraer la clave privada llevando a cabo un ataque de curva no válida.
