Vim allows to redirect screen messages using the `:redir` ex command to register, variables and files. It also allows to show the contents of registers using the `:registers` or `:display` ex command. When redirecting the output of `:display` to a register, Vim will free the register content before storing the new content in the register. Now when redirecting the `:display` command to a register that is being displayed, Vim will free the content while shortly afterwards trying to access it, which leads to a use-after-free. Vim pre 9.1.1115 checks in the ex_display() function, that it does not try to redirect to a register while displaying this register at the same time. However this check is not complete, and so Vim does not check the `+` and `*` registers (which typically donate the X11/clipboard registers, and when a clipboard connection is not possible will fall back to use register 0 instead. In Patch 9.1.1115 Vim will therefore skip outputting to register zero when trying to redirect to the clipboard registers `*` or `+`. Users are advised to upgrade. There are no known workarounds for this vulnerability."}, {"lang": "es", "value": "VIM es una versi\u00f3n muy mejorada del buen editor de Unix VI. VIM permite redirigir mensajes de pantalla utilizando el comando `: redir` ex para registrarse, variables y archivos.

Al redirigir la salida de `: Display` a un registro, VIM liberar\u00e1 el contenido de registro antes de almacenar el nuevo contenido en el registro. Ahora, al redirigir el comando `: Display` a un registro que se muestra, VIM liberar\u00e1 el contenido mientras que poco despu\u00e9s intenta acceder a \u00e9l, lo que conduce a un use-after-free. VIM PRE 9.1.1115 verifica la funci\u00f3n ex_display (), que no intenta redirigir a un registro al mostrar este registro al mismo tiempo. Sin embargo, esta verificaci\u00f3n no est\u00e1 completa, por lo que VIM no verifica los registros `+` y `*` que generalmente donan los registros X11/Portapaplos, y cuando una conexi\u00f3n de portapapeles no es posible volver\u00e1 a usar el registro 0. Patch 9.1.1115 VIM, por lo tanto, se saltar\u00e1 la salida para registrar cero al intentar redirigir a los registros de portapapeles `*` o `+`.
