La primera vulnerabilidad fue corregida sin gran publicidad en las versiones de marzo 7.4.6 y 7.5.1, y la segunda en las actualizaciones de mayo de LibreOffice 7.4.7 y 7.5.3.    <\/p>\n<p>La primera vulnerabilidad (CVE-2023-0950) permite potencialmente que se ejecute su c\u00f3digo en el sistema al abrir una hoja de c\u00e1lculo que contiene f\u00f3rmulas especialmente modificadas, como AGGREGATE, en las que se han pasado menos par\u00e1metros de los esperados. El problema es causado por un desbordamiento de \u00edndice de matriz a trav\u00e9s del l\u00edmite inferior (underflow) en el c\u00f3digo de an\u00e1lisis de f\u00f3rmulas (ScInterpreter) que se utiliza al procesar hojas de c\u00e1lculo.      <\/p>\n<p>La segunda vulnerabilidad (CVE-2023-2255) permite a un atacante preparar un documento especialmente dise\u00f1ado, que al abrirse cargar\u00e1 enlaces externos sin mostrar una solicitud ni advertencia, lo cual no corresponde al comportamiento declarado de LibreOffice que implica mostrar una advertencia al cargar contenido relacionado. El problema es causado por una falta de desarrollo en el c\u00f3digo de solicitud de permisos al utilizar el mecanismo \u00abFloating Frames\u00bb, similar a iframe en HTML y que permite incluir din\u00e1micamente contenido de archivos externos en el documento.<br \/>\n<br \/>Fuente: <a content=\"nofollow\" rel=\"nofollow\"
