Descriptions
The NTLM authentication feature in curl and libcurl before 7.57.0 on 32-bit platforms allows attackers to cause a denial of service (integer overflow and resultant buffer overflow, and application crash) or possibly have unspecified other impact via vectors involving long user and password fields.
La característica de autenticación NTLM en curl y libcurl en versiones anteriores a la 7.57.0 en plataformas de 32-bits permite que los atacantes provoquen una denegación de servicio (desbordamiento de enteros y desbordamiento de búfer resultante, y cierre inesperado de la aplicación) o que, posiblemente, causen otro tipo de impacto sin especificar mediante vectores relacionados con campos user y password largos.
