CVE-2026-25796

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, in `ReadSTEGANOImage()` (`coders/stegano.c`), the `watermark` Image object is not freed on three early-return paths, resulting in a definite memory leak (~13.5KB+ per invocation) that can be exploited for denial of service. Versions 7.1.2-15 and 6.9.13-40 contain a patch.

Summary		(es) ImageMagick es un software libre y de código abierto utilizado para editar y manipular imágenes digitales. Antes de las versiones 7.1.2-15 y 6.9.13-40, en 'ReadSTEGANOImage()' ('coders/stegano.c'), el objeto de imagen 'watermark' no se libera en tres rutas de retorno anticipado, lo que resulta en una fuga de memoria definida (~13.5KB+ por invocación) que puede ser explotada para denegación de servicio. Las versiones 7.1.2-15 y 6.9.13-40 contienen un parche.
