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.
Alex Nichols discovered that curl incorrectly handled NTLM authentication credentials. A remote attacker could use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 LTS, Ubuntu 17.04 and Ubuntu 17.10. It was discovered that curl incorrectly handled FTP wildcard matching. A remote attacker could use this issue to cause curl to crash, resulting in a denial of service, or possibly obtain sensitive information. Various other issues were also addressed.
