CVE-2010-2598

La libreria LibTIFF de Red Hat Enterprise Linux (RHEL) v3 sobre las plataformas x86_64, tal y como se utiliza en tiff2rgba, intenta de procesar los datos de la imagen incluso cuando la funcionalidad de compresión solicitado no está configurada, lo que permite a atacantes remotos provocar una denegación de servicio a través de una imagen TIFF debidamente modificada. Se trata de una vulnerabilidad relacionada con "downsampled OJPEG input".
