Descriptions

Multiple integer overflows in the (1) cvt_by_strip and (2) cvt_by_tile functions in the tiff2rgba tool in LibTIFF 4.0.6 and earlier, when -b mode is enabled, allow remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted TIFF image, which triggers an out-of-bounds write.

Múltiples desbordamientos de entero en las funciones (1) cvt_by_strip y (2) cvt_by_tile en la herramienta tiff2rgba en LibTIFF 4.0.6 y versiones anteriores, cuando está habilitado el modo -b, permiten a atacantes remotos provocar una denegación de servicio (caída) o ejecutar código arbitrario a través de una imagen TIFF manipulada, lo que desencadena una escritura fuera de límites.
