CVE-2014-8130

The _TIFFmalloc function in tif_unix.c in LibTIFF 4.0.3 does not reject a zero size, which allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted TIFF image that is mishandled by the TIFFWriteScanline function in tif_write.c, as demonstrated by tiffdither.

La función _TIFFmalloc en tif_unix.c en LibTIFF 4.0.3 no rechaza un tamaño cero, lo que permite que atacantes remotos provoquen una denegación de servicio (error de división entre cero y cierre inesperado de la aplicación) mediante una imagen TIFF manipulada que es gestionada incorrectamente por la función TIFFWriteScanline en tif_write.c, tal y como demuestra tiffdither.
