Vim is an open source, command line text editor. In versions from 9.1.1231 to before 9.1.1400, When processing nested tuples in Vim script, an error during evaluation can trigger a use-after-free in Vim’s internal tuple reference management. Specifically, the tuple_unref() function may access already freed memory due to improper lifetime handling, leading to memory corruption. The exploit requires direct user interaction, as the script must be explicitly executed within Vim. This issue has been patched in version 9.1.1400.

| Summary | (es) Vim es un editor de texto de línea de comandos de código abierto. En versiones desde la 9.1.1231 hasta anteriores a la 9.1.1400, al procesar tuplas anidadas en un script de Vim, un error durante la evaluación podía provocar un error de use after free en la gestión interna de referencias de tuplas de Vim. En concreto, la función tuple_unref() podía acceder a memoria ya liberada debido a una gestión incorrecta del tiempo de vida, lo que provocaba corrupción de memoria. Este exploit requiere la interacción directa del usuario, ya que el script debe ejecutarse explícitamente en Vim. Este problema se ha corregido en la versión 9.1.1400. |
