<impact type="normal">
|
|
<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 GNU Tar.

<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-arch/tar-1.18-r2"</code>
