Summary

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.
