<title>Samba: Heap-based buffer overflow</title>
A heap-based buffer overflow vulnerability was found in Samba, allowing for
the execution of arbitrary code.

<package name="net-fs/samba" auto="yes" arch="*">

<vulnerable range="lt">3.0.28a-r1</vulnerable>
Samba is a suite of SMB and CIFS client/server programs.
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.
<impact type="normal">
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.
There is no known workaround at this time.
All Samba users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-fs/samba-3.0.28a-r1&quot;</code>
