CVE-2026-56374

ImageMagick before 7.1.2-19 contains a heap buffer overflow vulnerability in the FTXT encoder due to missing boundary checks when parsing ftxt:format. Remote attackers can trigger an out of bounds read by crafting malicious FTXT image files to cause denial of service or information disclosure.

Summary		(es) ImageMagick anterior a la versión 7.1.2-19 contiene una vulnerabilidad de desbordamiento de búfer de pila en el codificador FTXT debido a la falta de comprobaciones de límites al analizar ftxt:format. Atacantes remotos pueden desencadenar una lectura fuera de límites al crear archivos de imagen FTXT maliciosos para causar denegación de servicio o revelación de información.
