Descriptions

An issue has been discovered in GitLab affecting all versions starting from 8.10 before 16.0.8, all versions starting from 16.1 before 16.1.3, all versions starting from 16.2 before 16.2.2. Under specific circumstances, a user importing a project 'from export' could access and read unrelated files via uploading a specially crafted file. This was due to a bug in `tar`, fixed in [`tar-1.35`](https://lists.gnu.org/archive/html/info-gnu/2023-07/msg00005.html).

Se ha descubierto un problema en GitLab que afecta a todas las versiones a partir de la 8.10 antes de la 16.0.8, todas las versiones a partir de la 16.1 antes de la 16.1.3, todas las versiones a partir de la 16.2 antes de la 16.2.2. En determinadas circunstancias, un usuario que importaba un proyecto "desde exportación" podía acceder a archivos no relacionados y leerlos mediante la carga de un archivo especialmente diseñado. Esto se debía a un error en `tar`, corregido en [`tar-1.35`](https://lists.gnu.org/archive/html/info-gnu/2023-07/msg00005.html).
