An exploitable heap-based buffer overflow exists in the handling of TIFF images in LibTIFF's TIFF2PDF tool. A crafted TIFF document can lead to a heap-based buffer overflow resulting in remote code execution. Vulnerability can be triggered via a saved TIFF file delivered by other means.
Existe un desbordamiento de búfer basado en memoria dinámica explotable en el manejo de imágenes TIFF en la herramienta LibTIFF's TIFF2PDF. Un documento TIFF manipulado puede conducir a un desbordamiento de búfer basado en memoria dinámica resultando en ejecución remota de código. La vulnerabilidad puede ser desencadenada a través de un archivo TIFF guardado entregado por otros medios.
The libtiff packages contain a library of functions for manipulating Tagged Image File Format files. Security Fix: Multiple flaws have been discovered in libtiff. A remote attacker could exploit these flaws to cause a crash or memory corruption and, possibly, execute arbitrary code by tricking an application linked against libtiff into processing specially crafted files.
