<description>
<p>
Alin Rad Pop (Secunia Research) reported a vulnerability in Samba
within the receive_smb_raw() function in the file lib/util_sock.c when
parsing SMB packets, possibly leading to a heap-based buffer overflow
via an overly large SMB packet.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could possibly exploit this vulnerability by enticing
a user to connect to a malicious server or by sending specially crafted
packets to an nmbd server configured as a local or domain master
browser, resulting in the execution of arbitrary code.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Samba users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-fs/samba-3.0.28a-r1&quot;</code>
</resolution>
