Albert Astals Cid reports:

+
Overview
+
A maliciously crafted TAR archive containing symlink entries + would install files anywhere in the user's home directory upon extraction.
+
Proof of concept
+
For testing, an example of malicious archive can be found at + dirsymlink.tar +
+
Impact
+
Users can unwillingly install files like a modified .bashrc, or a malicious + script placed in ~/.config/autostart.
+
Workaround
+
Before extracting a downloaded archive using the Ark GUI, users should inspect it + to make sure it doesn't contain symlink entries pointing outside the extraction folder.
+
The 'Extract' context menu from the Dolphin file manager shouldn't be used.
+
Solution
+
Ark 20.08.1 skips maliciously crafted symlinks when extracting TAR archives.
+
Alternatively, 8bf8c5ef07b0ac5e914d752681e470dea403a5bd can be applied to previous releases.
+
