Descriptions
A flaw was found in mbsync before v1.3.6 and v1.4.2, where an unchecked pointer cast allows a malicious or compromised server to write an arbitrary integer value past the end of a heap-allocated structure by issuing an unexpected APPENDUID response. This could be plausibly exploited for remote code execution on the client.
Se ha encontrado un fallo en mbsync versiones anteriores a v1.3.6 y v1.4.2, en el que un reparto de punteros no comprobado permite a un servidor malicioso o comprometido escribir un valor entero arbitrario más allá del final de una estructura asignada a la pila emitiendo una respuesta APPENDUID no esperada. Esto podría ser explotado de forma plausible para una ejecución de código remota en el cliente
