Descriptions

In LibTIFF 4.0.9, there is an uncontrolled resource consumption in the TIFFSetDirectory function of tif_dir.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted tif file. This occurs because the declared number of directory entries is not validated against the actual number of directory entries.

En LibTIFF 4.0.9, hay un consumo no controlado de recursos en la función TIFFSetDirectory de tif_dir.c. Los atacantes remotos pueden aprovechar esta vulnerabilidad para provocar una denegación de servicio (DoS) mediante un archivo tif manipulado. Esto ocurre debido a que el número declarado de entradas de directorio no se valida contra el número actual de entradas de directorio.

It was discovered that LibTIFF incorrectly handled certain malformed images. If a user or automated system were tricked into opening a specially crafted image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges.
