CVE-2025-55158

Vim is an open source, command line text editor. In versions from 9.1.1231 to before 9.1.1406, when processing nested tuples during Vim9 script import operations, an error during evaluation can trigger a double-free in Vim’s internal typed value (typval_T) management. Specifically, the clear_tv() function may attempt to free memory that has already been deallocated, due to improper lifetime handling in the handle_import / ex_import code paths. The vulnerability can only be triggered if a user explicitly opens and executes a specially crafted Vim script. This issue has been patched in version 9.1.1406.

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 9.1.1406, al procesar tuplas anidadas durante las operaciones de importación de scripts de Vim9, un error durante la evaluación puede provocar una doble liberación en la gestión interna de valores tipificados (typval_T) de Vim. En concreto, la función clear_tv() puede intentar liberar memoria ya desasignada debido a una gestión incorrecta del tiempo de vida en las rutas de código handle_import / ex_import. La vulnerabilidad solo se activa si un usuario abre y ejecuta explícitamente un script de Vim especialmente manipulado. Este problema se ha corregido en la versión 9.1.1406.
