CVE-2021-39212

Estado: ModificadaBaja (3.6)—

ImageMagick es un software libre que se entrega como una distribución binaria lista para ser ejecutada o como un código fuente que se puede usar, copiar, modificar y distribuir tanto en aplicaciones abiertas como propietarias. En las versiones afectadas y en determinados casos, los archivos Postscript podían leerse y escribirse cuando se excluían específicamente mediante una política de "module" en "policy.xml". ex. (policy domain="module" rights="none" pattern="PS" /). El problema ha sido resuelto en ImageMagick versiones 7.1.0-7 y en 6.9.12-22.

Leer descripción completaMostrar menos

Afortunadamente, en la naturaleza, pocos usuarios usan la política "module" y en su lugar usan la política "coder" que es también nuestra recomendación de solución: (policy domain="coder" rights="none" pattern="{PS,EPI,EPS,EPSF,EPSI}" /)
