Starting with 1.7.0, when a user clones an untrusted repository and runs gitk without additional command arguments, files for which the user has write permission can be created and truncated. The option Support per-file encoding must have been enabled before in Gitk's Preferences. This option is disabled by default. The same happens when Show origin of this line is used in the main window (regardless of whether Support per-file encoding is enabled or not). This vulnerability is fixed in 2.43.7, 2.44.4, 2.45.4, 2.46.4, 2.47.3, 2.48.2, 2.49.1, and 2.50.1."

A partir de la versión 1.7.0, cuando un usuario clona un repositorio no confiable y ejecuta Gitk sin argumentos de comando adicionales, se pueden crear y truncar archivos con permiso de escritura. La opción \"Compatibilidad con codificación por archivo\" debe estar habilitada previamente en las Preferencias de Gitk. Esta opción está deshabilitada por defecto. Lo mismo ocurre cuando se usa \"Mostrar el origen de esta línea\" en la ventana principal (independientemente de si \"Compatibilidad con codificación por archivo\" está habilitada o no). Esta vulnerabilidad está corregida en las versiones 2.43.7, 2.44.4, 2.45.4, 2.46.4, 2.47.3, 2.48.2, 2.49.1 y 2.50.1."
