Descriptions

fr-archive-libarchive.c in GNOME file-roller through 3.36.1 allows Directory Traversal during extraction because it lacks a check of whether a file's parent is a symlink to a directory outside of the intended extraction location.

El archivo fr-archive-libarchive.c en GNOME file-roller versiones hasta 3.36.1, permite un Salto del Directorio durante la extracción porque carece de una comprobación de si el padre de un archivo es un enlace simbólico en un directorio fuera de la ubicación de extracción prevista.

USN-4332-1 fixed vulnerabilities in File Roller. This update provides the corresponding update for Ubuntu 20.04 LTS. It was discovered that File Roller incorrectly handled symlinks. An attacker could possibly use this issue to expose sensitive information.
