En enero, Adobe lanzó cuatro parches que abordaban 29 CVE en Adobe Acrobat y Reader, InDesign, InCopy y Adobe Dimension. Un total de 22 de estos errores se registraron utilizando el programa ZDI. La actualización de Reader corrige 15 errores, ocho de los cuales están clasificados como críticos en cuanto a su gravedad. La vulnerabilidad más grave podría permitir la ejecución de código arbitrario si un sistema afectado abre un archivo especialmente diseñado.

El parche de InDesign corrige seis errores, cuatro de los cuales se clasifican como críticos. Al igual que con el parche de Reader, abrir un archivo malicioso puede provocar la ejecución de código. Lo mismo ocurre con InCopy, que también recibió correcciones para seis CVE. La actualización de Dimension solo aborda los dos CVE, pero las correcciones también incluyen actualizaciones de las dependencias de SketchUp. La versión anterior tiene una marca de tiempo del 22 de febrero, mientras que la versión lanzada hoy tiene una marca de tiempo del 9 de noviembre. Este mes, ningún error corregido de Adobe parece haber reconocido o atacado activamente abiertamente. Adobe clasificó estas actualizaciones como clasificación de prioridad. Parche de enero de 2023 de Microsoft

Este mes, Microsoft lanzó 98 nuevos parches que abordan CVE en Microsoft Windows y componentes de Windows; Oficina y componentes de oficina; .NET Core y Visual Studio Code, 3D Builder, Azure Service Fabric Containers, Windows BitLocker, Windows Defender, componentes de Windows Print Spooler y Microsoft Exchange Server. Un total de 25 de estos CVE se enviaron a través del programa ZDI. De los 98 nuevos parches lanzados hoy, 11 fueron calificados como críticos y 87 como críticos. Esa cantidad es el mayor lanzamiento de enero que hemos visto de Microsoft en mucho tiempo. Será interesante ver si este volumen de enmienda continuará durante todo el año.

Uno de los nuevos CVE, que se descubrió este mes se muestra como conocido públicamente, y uno figura como en la naturaleza en el momento del lanzamiento. Echemos un vistazo más de cerca a algunas de las actualizaciones más interesantes de este mes, comenzando con las vulnerabilidades más explotadas:
