+ <h3>Overview</h3>
+ <p>A maliciously crafted TAR archive containing symlink entries
+ would install files anywhere in the user's home directory upon extraction.</p>
+ <h3>Proof of concept</h3>
+ <p>For testing, an example of malicious archive can be found at
+ <a href="https://github.com/jwilk/traversal-archives/releases/download/0/dirsymlink.tar">dirsymlink.tar</a>
+ </p>
+ <h3>Impact</h3>
+ <p>Users can unwillingly install files like a modified .bashrc, or a malicious
+ script placed in ~/.config/autostart.</p>
+ <h3>Workaround</h3>
+ <p>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.</p>
+ <p>The 'Extract' context menu from the Dolphin file manager shouldn't be used.</p>
+ <h3>Solution</h3>
+ <p>Ark 20.08.1 skips maliciously crafted symlinks when extracting TAR archives.</p>
+ <p>Alternatively, <a href="https://invent.kde.org/utilities/ark/-/commit/8bf8c5ef07b0ac5e914d752681e470dea403a5bd">8bf8c5ef07b0ac5e914d752681e470dea403a5bd</a> can be applied to previous releases.</p>
+ <h3>Credits</h3>
+ <p>Thanks to Fabian Vogt for reporting this issue and for fixing it.</p>
