CVE-2010-3947

Desbordamiento de búfer basado en memoria dinámica (heap) en el convertidor de imágenes TIFF en Microsoft Office XP SP3, Office Converter Pack, y Works 9, permite a atacantes remotos ejecutar código de su elección a través de una imagen TIFF manipulada en un documento de Office. También conocida como "TIFF Image Converter Heap Overflow Vulnerability".

Secunia Research has discovered two vulnerabilities in Microsoft Office, which can be exploited by malicious people to compromise a user's system. An input validation error in the TIFF Import/Export Graphic Filter when copying certain data can be exploited to cause a heap-based buffer overflow via a specially crafted TIFF image. Another input validation error in the TIFF Import/Export Graphic Filter when copying certain data after having encountered a specific error can be exploited to cause a heap-based buffer overflow via a specially crafted TIFF image. Successful exploitation of the vulnerabilities may allow execution of arbitrary code when processing a TIFF image in an application using the graphics filter (e.g. opening the image in Microsoft Photo Editor or importing it into an Office document).
