CVE-2025-48379

Pillow is a Python imaging library. In versions 11.2.0 to before 11.3.0, there is a heap buffer overflow when writing a sufficiently large (>64k encoded with default settings) image in the DDS format due to writing into a buffer without checking for available space. This only affects users who save untrusted data as a compressed DDS image. This issue has been patched in version 11.3.0.

Summary		(es) Pillow es una librería de imágenes de Python. En las versiones 11.2.0 y anteriores a la 11.3.0, se produce un desbordamiento del búfer de montón al escribir una imagen suficientemente grande (más de 64k codificada con la configuración predeterminada) en formato DDS, debido a que se escribe en un búfer sin comprobar el espacio disponible. Esto solo afecta a los usuarios que guardan datos no confiables como una imagen DDS comprimida. Este problema se ha corregido en la versión 11.3.0.
