The Star program provides the ability to create and extract tar
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
<impact type="low">
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.
There is no known workaround at this time.
All Star users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-arch/star-1.5_alpha84&quot;</code>
