Descriptions

The _TIFFVGetField function in tif_dirinfo.c in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (out-of-bounds write) or execute arbitrary code via a crafted TIFF image.

La función _TIFFVGetField en tif_dirinfo.c en LibTIFF 4.0.6 y versiones anteriores permite a atacantes remotos provocar una denegación de servicio (escritura fuera de límites) o ejecutar código arbitrario a través de una imagen TIFF manipulada.

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.
