      "value": "ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-9 and 6.9.13-34, there is a vulnerability in ImageMagick’s Magick++ layer that manifests when Options::fontFamily is invoked with an empty string. Clearing a font family calls RelinquishMagickMemory on _drawInfo->font, freeing the font string but leaving _drawInfo->font pointing to freed memory while _drawInfo->family is set to that (now-invalid) pointer. Any later cleanup or reuse of _drawInfo->font re-frees or dereferences dangling memory. DestroyDrawInfo and other setters (Options::font, Image::font) assume _drawInfo->font remains valid, so destruction or subsequent updates trigger crashes or heap corruption. This vulnerability is fixed in 7.1.2-9 and 6.9.13-34."

      "value": "ImageMagick es un software libre y de código abierto utilizado para editar y manipular imágenes digitales. Versiones anteriores a 7.1.2-9 y 6.9.13-34, existe una vulnerabilidad en la capa Magick++ de ImageMagick que se manifiesta cuando se invoca Options::fontFamily con una cadena vacía. Al borrar una familia de fuentes, se llama a RelinquishMagickMemory en _drawInfo -> font, liberando la cadena de la fuente pero dejando _drawInfo -> font apuntando a memoria liberada, mientras que _drawInfo -> family se establece a ese puntero (ahora inválido). Cualquier limpieza o reutilización posterior de _drawInfo -> font vuelve a liberar o desreferencia memoria colgante. DestroyDrawInfo y otros setters (Options::font, Image::font) asumen que _drawInfo -> font permanece válido, por lo que la destrucción o las actualizaciones posteriores desencadenan fallos o corrupción del heap. Esta vulnerabilidad se ha corregido en 7.1.2-9 y 6.9.13-34."
