Descriptions

fr-archive-libarchive.c in GNOME file-roller through 3.38.0, as used by GNOME Shell and other software, allows Directory Traversal during extraction because it lacks a check of whether a file's parent is a symlink in certain complex situations. NOTE: this issue exists because of an incomplete fix for CVE-2020-11736.

El archivo fr-archive-libarchive.c en GNOME file-roller versiones hasta 3.38.0, como es usado GNOME Shell y otro software, permite un Salto de Directorio durante una extracción porque carece de una comprobación de si el parent de un archivo es un enlace simbólico en determinadas situaciones complejas. NOTA: este problema se presenta debido a una corrección incompleta para CVE-2020-11736
