|
|
Luigi Auriemma has discovered multiple vulnerabilities in NAS, some of
|
|
which include a buffer overflow in the function accept_att_local(), an
|
|
integer overflow in the function ProcAuWriteElement(), and a null
|
|
pointer error in the function ReadRequestFromClient().
|
|

|
<impact type="high">
|
|
<p>
|
|
An attacker having access to the NAS daemon could send an overly long
|
|
slave name to the server, leading to the execution of arbitrary code
|
|
with root privileges. A remote attacker could also send a specially
|
|
crafted packet containing an invalid client ID, which would crash the
|
|
server and result in a Denial of Service.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All NAS users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-libs/nas-1.8b"</code>
|
|
