Vulnerability Name:

CVE-2021-28650 (CCN-198306)

Assigned:2021-03-01
Published:2021-03-01
Updated:2022-05-20
Summary:autoar-extractor.c in GNOME gnome-autoar before 0.3.1, as used by GNOME Shell, Nautilus, 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-2020-36241.
