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 ">=app-arch/star-1.5_alpha84"</code>
