FKIE_CVE-2018-3984

Vulnerability from fkie_nvd - Published: 2018-10-01 20:29 - Updated: 2024-11-21 04:06
Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Summary
An exploitable uninitialized length vulnerability exists within the Word document-parser of the Atlantis Word Processor 3.0.2.3 and 3.0.2.5. A specially crafted document can cause Atlantis to skip initializing a value representing the number of columns of a table. Later, the application will use this as a length within a loop that will write to a pointer on the heap. Due to this value being controlled, a buffer overflow will occur, which can lead to code execution under the context of the application. An attacker must convince a victim to open a document in order to trigger this vulnerability.

Un documento especialmente manipulado puede provocar que Atlantis se salte la inicializaci\u00f3n de un valor que representa el n\u00famero de columnas de una tabla. Despu\u00e9s, la aplicaci\u00f3n emplear\u00e1 esto como longitud en un bucle que escribir\u00e1 a un puntero en la memoria din\u00e1mica (heap). Debido a que este valor est\u00e1 controlado, ocurrir\u00e1 un desbordamiento de b\u00fafer, lo que puede conducir a la ejecuci\u00f3n de c\u00f3digo bajo el contexto de la aplicaci\u00f3n. Un atacante debe convencer a una v\u00edctima para que abra un documento para provocar esta vulnerabilidad."
