CVE-2012-1149

Un desbordamiento de entero en el módulo de vclmi.dll en OpenOffice.org (OOo) v3.3, v3.4 Beta, y posiblemente en versiones anteriores, y LibreOffice antes de v3.5.3, permite a atacantes remotos causar una denegación de servicio (caída de la aplicación) y posiblemente ejecutar código de su elección a través de un objeto de imagen especificamente modificado para este fin incrustado en el documento, tal y como lo demuestra una imagen JPEG en un archivo .DOC, que provoca un desbordamiento de búfer basado en memoria dinámica (heap).

A stack-based buffer overflow was discovered in the Lotus Word Pro import filter in OpenOffice.org. The default compiler options for affected releases should reduce the vulnerability to a denial of service. Huzaifa Sidhpurwala discovered that OpenOffice.org could be made to crash if it opened a specially crafted Word document. Integer overflows were discovered in the graphics loading code of several different image types. If a user were tricked into opening a specially crafted file, an attacker could cause OpenOffice.org to crash or possibly execute arbitrary code with the privileges of the user invoking the program. Various other issues were also addressed.
