CVE-2025-9900
Full vulnerability record from the local CVENow database.
Description
A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.

"value": "Se encontró una falla en Libtiff. Esta vulnerabilidad es una condición de “write-what-where”, que se activa cuando la biblioteca procesa un archivo de imagen TIFF especialmente diseñado.\n\nAl proporcionar un valor de altura de imagen anormalmente grande en los metadatos del archivo, un atacante puede engañar a la biblioteca para que escriba datos de color controlados por el atacante en una ubicación de memoria arbitraria. Esta corrupción de memoria puede ser explotada para causar una denegación de servicio (cierre inesperado de la aplicación) o para lograr ejecución de código arbitrario con los permisos del usuario."
