CVE-2026-25983

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, a crafted MSL script triggers a heap-use-after-free. The operation element handler replaces and frees the image while the parser continues reading from it, leading to a UAF in ReadBlobString during further parsing. 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, un script MSL manipulado desencadena un uso después de liberación en el heap. El gestor del elemento de operación reemplaza y libera la imagen mientras el analizador continúa leyendo de ella, lo que lleva a un UAF en ReadBlobString durante un análisis posterior. Las versiones 7.1.2-15 y 6.9.13-40 contienen un parche.
