CVE-2026-2272
Full vulnerability record from the local CVENow database.
Description
A flaw was found in GIMP. An integer overflow vulnerability exists when processing ICO image files, specifically in the `ico_read_info` and `ico_read_icon` functions. This issue arises because a size calculation for image buffers can wrap around due to a 32-bit integer evaluation, allowing oversized image headers to bypass security checks. A remote attacker could exploit this by providing a specially crafted ICO file, leading to a buffer overflow and memory corruption, which may result in an application level denial of service.

"value": "Se encontró una falla en GIMP. Existe una vulnerabilidad de desbordamiento de entero al procesar archivos de imagen ICO, específicamente en las funciones `ico_read_info` e `ico_read_icon`. Este problema surge porque un cálculo de tamaño para los búferes de imagen puede dar la vuelta debido a una evaluación de entero de 32 bits, permitiendo que los encabezados de imagen sobredimensionados eludan las comprobaciones de seguridad. Un atacante remoto podría explotar esto proporcionando un archivo ICO especialmente diseñado, lo que lleva a un desbordamiento de búfer y corrupción de memoria, lo que puede resultar en una denegación de servicio a nivel de aplicación."
