> Title : Samba Security Vulnerability
> Number : 20030403-01-P
> Date : April 9, 2003
> Reference: CVE CAN-2003-0201
> Reference: SGI BUG 886996
> Fixed in : Samba 2.2.8a or patch 5065
> ______________________________________________________________________________
>
> - -----------------------
> - --- Issue Specifics ---
> - -----------------------
>
> It's been reported that there is a vulnerability in Samba versions up to and
> including Samba 2.2.8. This vulnerability, if exploited correctly, leads to
> an anonymous user gaining root access on a Samba serving system.
>
> See: http://master.samba.org/samba/samba.html (Samba News 7 Apr, 2003)
> http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0201
>
> SGI has investigated the issue and recommends the following steps for
> neutralizing the exposure. It is HIGHLY RECOMMENDED that these measures be
> implemented on ALL vulnerable SGI systems.
>
> These issues have been corrected in future releases of Samba and with a
> patch for SGI's Samba 2.2.8.
>

> - --------------
> - --- Impact ---
> - --------------
>
> Samba for Irix is not installed by default on IRIX 6.5 systems. It is an
> optional product that can be purchased and installed as "samba_irix".
>
> To determine the version of IRIX you are running, execute the following
> command:
>
> # /bin/uname -R
>
> That will return a result similar to the following:
>
> # 6.5 6.5.19f
>
> The first number ("6.5") is the release name, the second ("6.5.16f" in this
> case) is the extended release name. The extended release name is the
> "version" we refer to throughout this document.
>
> To see if Samba is installed, execute the following command:
>
> % versions samba_irix
> I = Installed, R = Removed
>
> Name Date Description
>
> I samba_irix 07/02/2002 Samba 2.2.4 for IRIX
> I samba_irix.man 07/02/2002 Samba Online Documentation
> I samba_irix.man.doc 07/02/2002 Samba 2.2.4 Documentation
> I samba_irix.man.manpages 07/02/2002 Samba 2.2.4 Man Page
> I samba_irix.man.relnotes 07/02/2002 Samba 2.2.4 Release Notes
> I samba_irix.src 07/02/2002 Samba Source Code
> I samba_irix.src.samba 07/02/2002 Samba 2.2.4 Source Code
> I samba_irix.sw 07/02/2002 Samba Execution Environment
> I samba_irix.sw.base 07/02/2002 Samba 2.2.4 Execution Environment
>
> If the result is similar to the above and the version shown is less than
> 2.2.8a, then the system is vulnerable.
>
>
> - ----------------------------
> - --- Temporary Workaround ---
> - ----------------------------
>
> Though it is possible to limit exposure by filtering what IPs can talk to
> your Samba server, there is no effective workaround to fully address these
> problems. SGI recommends upgrading to Samba 2.2.8 and installing patch 5065.
>
>
> - ----------------
> - --- Solution ---
> - ----------------
>
> SGI has provided a patch for Samba 2.2.8 for this vulnerability. Our
> recommendation is to upgrade to Samba 2.2.8 and install the patch.
>
> Patch 5065 only applies to the samba_irix 2.2.8 package.
> This patch will not apply to the freeware versions of samba available from:
> http://freeware.sgi.com/ , http://www.samba.org/ and
> http://master.samba.org/samba/ftp/Binary_Packages/IRIX/
