<background>
|
|
<p>The RPCBind utility is a server that converts RPC program numbers into
|
|
universal addresses.
|
|
</p>
|
|
|
|
<p>Libtirpc is a port of Suns Transport-Independent RPC library to Linux.</p>
|
|
</background>
|
|
<description>
|
|
<p>It was found that due to the way RPCBind uses libtirpc (libntirpc), a
|
|
memory leak can occur when parsing specially crafted XDR messages.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>A remote attacker could send thousands of messages to RPCBind, possibly
|
|
resulting in a Denial of Service condition.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All RPCBind users should upgrade to the latest version:</p>
|

|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-nds/rpcbind-0.2.4-r1"
