<description>

|
<p>
|
|
A vulnerability has been found in cpio that can potentially allow
|
|
a cpio archive to extract its files to an arbitrary directory of the
|
|
creator's choice.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
An attacker could create a malicious cpio archive which would
|
|
create files in arbitrary locations on the victim's system. This issue
|
|
could also be used in conjunction with a previous race condition
|
|
vulnerability (CAN-2005-1111) to change permissions on files owned by
|
|
the victim.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All cpio users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-arch/cpio-2.6-r3"</code>
|
|
</resolution>
