Descriptions
The push_ascii function in smbd in Samba 3.6.x before 3.6.24, 4.0.x before 4.0.19, and 4.1.x before 4.1.9 allows remote authenticated users to cause a denial of service (memory corruption and daemon crash) via an attempt to read a Unicode pathname without specifying use of Unicode, leading to a character-set conversion failure that triggers an invalid pointer dereference.
La función push_ascii en smbd en Samba 3.6.x anterior a 3.6.24, 4.0.x anterior a 4.0.19 y 4.1.x anterior a 4.1.9 permite a usuarios remotos autenticados causar una denegación de servicio (corrupción de memoria y caída de demonio) a través de in intento de leer un nombre de ruta Unicode sin especificar el uso de Unicode, que conduce a un fallo de conversión de configuración de carácter que provoca una referencia a puntero inválida.
It was discovered that smbd, the Samba file server daemon, did not properly handle certain files that were stored on the disk and used a valid Unicode character in the file name. An attacker able to send an authenticated non-Unicode request that attempted to read such a file could cause smbd to crash.
