<description>
<p>
Robert Buchholz of the Gentoo Security team discovered a directory
traversal vulnerability in the has_dotdot() function which does not
identify //.. (slash slash dot dot) sequences in file names inside tar
files.
</p>
</description>
<impact type="low">
<p>
By enticing a user to extract a specially crafted tar archive, a remote
attacker could extract files to arbitrary locations outside of the
specified directory with the permissions of the user running Star.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Star users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-arch/star-1.5_alpha84&quot;</code>
</resolution>
