<p>
|
|
The Tar program provides the ability to create and manipulate tar
|
|
archives.

|
<p>
|
|
Tar does not properly extract archive elements using the GNUTYPE_NAMES
|
|
record name, allowing files to be created at arbitrary locations using
|
|
symlinks. Once a symlink is extracted, files after the symlink in the
|
|
archive will be extracted to the destination of the symlink.
|
|

<impact type="normal">
|
|
<p>
|
|
An attacker could entice a user to extract a specially crafted tar
|
|
archive, possibly allowing for the overwriting of arbitrary files on
|
|
the system extracting the archive.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Tar users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-arch/tar-1.16-r2"</code>
