Hi,

The following vulnerability was published for gnome-autoar.

CVE-2020-36241[0]:
| autoar-extractor.c in GNOME gnome-autoar through 0.2.4, 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 to a directory outside of the intended extraction
| location.

If possible this ideally should be fixed in bullseye in time.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
