Sun(sm) Alert Notification

* Synopsis: Security Vulnerability in Samba(7) Versions Prior to
3.0.10 May Allow Unauthorized Root Privileges
* Category: Security
* Product: Solaris 9 Operating System, Solaris 10 Operating System
* BugIDs: 6217228

1. Impact
An integer overflow security issue with the Samba(7) smbd(1m) daemon
may allow a local or remote authenticated user the ability to execute
arbitrary commands with the privileges of Super User (typically root),
on a Solaris 9 or Solaris 10 system running as a Samba(7) server.
More information on this issue is available at:
* CERT Vulnerability Note VU#226184 at:
http://www.kb.cert.org/vuls/id/226184
* CVE CAN-2004-1154 at:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-1154
* Samba Security Announcement at:
http://www.samba.org/samba/security/CAN-2004-1154.html
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* Solaris 9 without patch 114684-05
* Solaris 10 without patch 119757-01
x86 Platform
* Solaris 9 without patch 114685-05
* Solaris 10 without patch 119758-01
Note: Solaris 7 and Solaris 8 do not include the Samba software and
are not affected by this issues. Sun does include Samba on the Solaris
Companion CD for Solaris 8 as an unsupported package which installs to
"/opt/sfw" and is vulnerable to this issue. Sites using the freeware
version of Samba from the Solaris Companion CD will need to upgrade to
a later version from Samba.org.
This issue only occurs if all of the following conditions are true:
* The system is configured as a Samba server
* The version of Samba installed is 2.X through 3.0.9
To determine if a system is configured as a Samba server, use the
following command to check for the presence of the smb.conf(4) file:
% ls -l /etc/sfw/smb.conf
-rw-r--r-- 1 root other 11665 Sep 28 16:37 /etc/sfw/smb.conf
If the output is similar to that shown above, the system is configured
as a Samba server.
To determine the version of Samba installed on a system, the following
command can be run:
% /usr/sfw/sbin/smbd -V
Version 3.0.4
3. Symptoms
Unsuccessful exploitation attempts may leave evidence of an attack in
system logs.
4. Relief/Workaround
To work around the described issue, download and compile samba 3.0.10
or higher from Samba.org
Follow the security suggestions from the samba team at:
http://www.samba.org/samba/docs/server_security.html.
5. Resolution
This issue is addressed in the following releases:
SPARC Platform
* Solaris 9 with patch 114684-05 or later
* Solaris 10 with patch 119757-01 or later
x86 Platform
* Solaris 9 with patch 114685-05 or later
