Esta vulnerabilidad podr\u00eda llevar a la ejecuci\u00f3n remota de c\u00f3digo en <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/es\/server\/dts-newyork\/\"   title=\"servidor\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2763\">servidor<\/a>. El problema se manifiesta a partir de Redis 2.6 y se ha solucionado en las versiones 7.0.12, 6.2.13 y 6.0.20. Como soluci\u00f3n provisional, se puede evitar que los usuarios de Redis ejecuten los comandos EVAL y EVALSHA a trav\u00e9s de ACL.\n<li class=\"l\"> CVE-2023-36824 \u2014 vulnerabilidad en la base de datos Redis que causa un desbordamiento de b\u00fafer al procesar nombres de claves enviados a trav\u00e9s de los comandos COMMAND GETKEYS o COMMAND GETKEYSANDFLAGS, as\u00ed como listas de claves en las reglas de ACL. Potencialmente, esta vulnerabilidad podr\u00eda permitir la ejecuci\u00f3n remota de c\u00f3digo en el servidor. El problema solo se manifiesta en la rama 7.0.x y se ha solucionado en la versi\u00f3n 7.0.12.\n<li class=\"l\"> CVE-2022-23537 \u2014 vulnerabilidad en la plataforma de comunicaci\u00f3n Asterisk que provoca un desbordamiento de buffer durante el an\u00e1lisis <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/es\/server\/dts-prohoster\/\"   title=\"el servidor\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3076\">el servidor<\/a> mensajes STUN malformados que contienen un atributo desconocido. El problema se manifiesta al utilizar protocolos ICE o WebRTC en Asterisk. La vulnerabilidad ha sido corregida en las versiones 16.30.1, 18.18.1, 19.8.1 y 20.3.1.\n<li class=\"l\"> CVE-2023-36664 \u2014 vulnerabilidad en Ghostscript, un conjunto de herramientas para procesar, convertir y generar documentos en los formatos PostScript y PDF, que permite ejecutar c\u00f3digo arbitrario al abrir documentos maliciosos en formato PostScript. El problema es causado por un manejo incorrecto de los nombres de archivo que comienzan con el car\u00e1cter \u00ab|\u00bb o el prefijo %pipe%. La vulnerabilidad ha sido corregida en la versi\u00f3n Ghostscript 10.01.2.\n<p>En muchos entornos, Ghostscript se invoca durante la creaci\u00f3n de miniaturas en el escritorio o durante la indexaci\u00f3n en segundo plano, por lo que en ocasiones basta con cargar un archivo con un exploit o visualizar el directorio que lo contiene en Nautilus. Un ataque a los sistemas del servidor puede organizarse a trav\u00e9s de controladores de im\u00e1genes basados en ImageMagick y GraphicsMagick, que invocan Ghostscript al procesar archivos JPEG o PNG que contienen c\u00f3digo PostScript en lugar de una imagen (dicha archivo ser\u00e1 procesado por Ghostscript, ya que el tipo MIME se reconoce por su contenido, no confiando en la extensi\u00f3n).    <\/p>\n<li class=\"l\"> CVE-2023-36475 \u2014 vulnerabilidad en Parse Server, un backend para Node.js que trabaja con el marco web Express, que permite ejecutar c\u00f3digo de forma remota en el servidor. La vulnerabilidad permite aplicar el m\u00e9todo de contaminaci\u00f3n de prototipos de objetos JavaScript (\u00abprototype pollution\u00bb) para ejecutar c\u00f3digo a trav\u00e9s del analizador BSON de MongoDB. Esta vulnerabilidad ha sido clasificada con un nivel de peligro de 9.8 sobre 10. El problema ha sido corregido en las actualizaciones de parse-server 5.5.2 y 6.2.1.      <\/ul>\n<p>Fuente: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=59430\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041d\u0435\u0441\u043a\u043e\u043b\u044c\u043a\u043e \u043d\u0435\u0434\u0430\u0432\u043d\u043e \u0432\u044b\u044f\u0432\u043b\u0435\u043d\u043d\u044b\u0445 \u043e\u043f\u0430\u0441\u043d\u044b\u0445 \u0443\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u0435\u0439: CVE-2022-24834 &#8212; \u0443\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u044c \u0432 \u0421\u0423\u0411\u0414 Redis, \u043f\u043e\u0437\u0432\u043e\u043b\u044f\u044e\u0449\u0430\u044f \u0432\u044b\u0437\u0432\u0430\u0442\u044c \u043f\u0435\u0440\u0435\u043f\u043e\u043b\u043d\u0435\u043d\u0438\u0435 \u0431\u0443\u0444\u0435\u0440\u0430 \u0432 \u0431\u0438\u0431\u043b\u0438\u043e\u0442\u0435\u043a\u0430\u0445 cjson \u0438 cmsgpack \u043f\u0440\u0438 \u0432\u044b\u043f\u043e\u043b\u043d\u0435\u043d\u0438\u0438 \u0441\u043f\u0435\u0446\u0438\u0430\u043b\u044c\u043d\u043e \u043e\u0444\u043e\u0440\u043c\u043b\u0435\u043d\u043d\u043e\u0433\u043e \u0441\u0446\u0435\u043d\u0430\u0440\u0438\u044f \u043d\u0430 \u044f\u0437\u044b\u043a\u0435 Lua. \u041f\u043e\u0442\u0435\u043d\u0446\u0438\u0430\u043b\u044c\u043d\u043e \u0443\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u044c \u043c\u043e\u0436\u0435\u0442 \u043f\u0440\u0438\u0432\u0435\u0441\u0442\u0438 \u043a \u0443\u0434\u0430\u043b\u0451\u043d\u043d\u043e\u043c\u0443 \u0432\u044b\u043f\u043e\u043b\u043d\u0435\u043d\u0438\u044e \u043a\u043e\u0434\u0430 \u043d\u0430 \u0441\u0435\u0440\u0432\u0435\u0440\u0435. \u041f\u0440\u043e\u0431\u043b\u0435\u043c\u0430 \u043f\u0440\u043e\u044f\u0432\u043b\u044f\u0435\u0442\u0441\u044f \u043d\u0430\u0447\u0438\u043d\u0430\u044f \u0441 Redis 2.6 \u0438 \u0443\u0441\u0442\u0440\u0430\u043d\u0435\u043d\u0430 \u0432 \u0432\u044b\u043f\u0443\u0441\u043a\u0430\u0445 7.0.12, 6.2.13 \u0438 6.0.20. \u0412 \u043a\u0430\u0447\u0435\u0441\u0442\u0432\u0435 \u043e\u0431\u0445\u043e\u0434\u043d\u043e\u0433\u043e [&hellip;]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-109367","post","type-post","status-publish","format-standard","hentry","category-news"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.2 -
