CVE-2020-36241

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.

Automatic archives creating and extracting library.

Yiğit Can Yılmaz discovered that GNOME Autoar could extract files outside of the intended directory. If a user were tricked into extracting a specially crafted archive, a remote attacker could create files in arbitrary locations, possibly leading to code execution (CVE-2020-36241).

This update for gnome-autoar fixes the following issues:

• CVE-2020-36241: Skip problematic files that might be extracted outside of the destination dir to prevent potential directory traversal (bsc#1181930).

This update was imported from the SUSE:SLE-15:Update update project.

These are all security issues fixed in the gnome-autoar-devel-0.4.0-1.3 package on the GA media of openSUSE Tumbleweed.
