CVE-2026-30937

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, a 32-bit unsigned integer overflow in the XWD (X Windows) encoder can cause an undersized heap buffer allocation. When writing a extremely large image an out of bounds heap write can occur. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.

Summary		(es) ImageMagick es un software libre y de código abierto utilizado para editar y manipular imágenes digitales. Antes de las versiones 7.1.2-16 y 6.9.13-41, un desbordamiento de entero sin signo de 32 bits en el codificador XWD (X Windows) puede causar una asignación de búfer de pila de tamaño insuficiente. Al escribir una imagen extremadamente grande, puede ocurrir una escritura de pila fuera de límites. Esta vulnerabilidad está corregida en 7.1.2-16 y 6.9.13-41.
