Integer overflow in tools/bmp2tiff.c in LibTIFF before 4.0.4 allows remote attackers to cause a denial of service (heap-based buffer over-read), or possibly obtain sensitive information from process memory, via crafted width and length values in RLE4 or RLE8 data in a BMP file.
Desbordamiento de entero en tools/bmp2tiff.c en LibTIFF en versiones anteriores a 4.0.4 permite a atacantes remotos provocar una denegación de servicio (sobre lectura de búfer basado en memoria dinámica), o posiblemente obtener información sensible de la memoria de proceso, a través de valores de anchura y longitud manipulados en datos RLE4 o RLE8 en un archivo BMP.
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.
