<title>Samba: Multiple vulnerabilities</title>
|
|
<synopsis>
|
|
Samba is vulnerable to a buffer overflow that could lead to execution of
|
|
arbitrary code (CAN-2004-0882). Another flaw in Samba may allow a remote
|
|
attacker to cause a Denial of Service by excessive consumption of CPU
|
|
cycles (CAN-2004-0930).

Samba is a freely available SMB/CIFS implementation which allows
|
|
seamless interoperability of file and print services to other SMB/CIFS
|
|
clients.

<description>

|
<p>
|
|
Samba fails to do proper bounds checking when handling
|
|
TRANSACT2_QFILEPATHINFO replies. Additionally an input validation flaw
|
|
exists in ms_fnmatch.c when matching filenames that contain wildcards.
|

<impact type="normal">
|
|
<p>
|
|
An attacker may be able to execute arbitrary code with the permissions
|
|
of the user running Samba. A remote attacker may also be able to cause
|
|
an abnormal consumption of CPU resources, resulting in slower
|
|
performance of the server or even a Denial of Service.
|
|
</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 ">=net-fs/samba-3.0.8"</code>
|
|
</resolution>
