CVE-2018-4001

An exploitable uninitialized pointer vulnerability exists in the Office Open XML parser of Atlantis Word Processor, version 3.2.5.0. A specially crafted document can cause an uninitialized pointer representing a TTableRow to be assigned to a variable on the stack. This variable is later dereferenced and then written to allow for controlled heap corruption, 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.

Existe una vulnerabilidad explotable de puntero sin inicializar en el analizador de XML de Open Office de Atlantis Word Processor 3.2.5.0. Un documento especialmente manipulado puede provocar que un puntero sin inicializar que representa un TTableRow se asigne a una variable de la pila. Después, esta variable se desreferencia y se escribe para permitir una corrupción controlada de la memoria dinámica (heap), lo que puede conducir a la ejecución de código en el contexto de la aplicación. Un atacante debe convencer a una víctima para que abra un documento para provocar esta vulnerabilidad.
