Descriptions

When opening a Hangul HShow Document (.hpt) and processing a structure within the document, Hancom Office 2014 will use a static size to allocate a heap buffer yet explicitly trust a size from the file when modifying data inside of it. Due to this, an aggressor can corrupt memory outside the bounds of this buffer which can lead to code execution under the context of the application.

Cuando se abre un Hangul HShow Document (.hpt) y se procesa una estructura dentro del documento, Hancom Office 2014 utilizará un tamaño estático para ubicar un búfer de memoria dinámica que aún confía explícitamente un tamaño del archivo cuando se modifican datos dentro de él. Debido a esto, un agresor puede corromper memoria fuera de límites de este búfer, lo que puede conducir a ejecución de código bajo el contexto de la aplicación.
