Samba client messaging functions, allowing a Linux desktop to
communicate with a Microsoft Windows computer that runs Winpopup.

<p>
Stephen Dranger discovered that LinPopUp contains a buffer
overflow in string.c, triggered when replying to a remote user message.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could craft a malicious message that, when
replied using LinPopUp, would exploit the buffer overflow. This would
result in the execution of arbitrary code with the privileges of the
user running LinPopUp.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All LinPopUp users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-im/linpopup-2.0.4-r1&quot;</code>
</resolution>
