Overview

A remotely exploitable buffer overflow has been discovered in the Solaris X Window Font Service (XFS) daemon (fs.auto).

Description

ISS X-Force released an Advisory today regarding a remotely exploitable buffer overflow in XFS. According to ISS, XFS is installed and running by default on the following operating systems and architectures:

* Sun Microsystems Solaris 2.5.1 (Sparc/Intel)
* Sun Microsystems Solaris 2.6 (Sparc/Intel)
* Sun Microsystems Solaris 7 (Sparc/Intel)
* Sun Microsystems Solaris 8 (Sparc/Intel)
* Sun Microsystems Solaris 9 (Sparc)
* Sun Microsystems Solaris 9 Update 2 (Intel)

According to the ISS Advisory, the buffer overflow exists in the fs.auto `Dispatch()` function. Because this function accepts user supplied data, an attacker can send overly large XFS queries to the XFS service and either cause it to crash or execute arbitrary code with the same privileges as the XFS service (typically nobody).

Impact

A remote attacker can execute arbitrary code with the privileges of the fs.auto daemon (typically nobody) or cause a denial of service by crashing the service.

Solution

Apply a vendor patch when it becomes available.

Ingress Filtering - It may be possible to limit the scope of this vulnerability by applying ingress filtering (blocking access to TCP port 7100 at your network perimeter). Note: You should carefully consider the impact of blocking services that you may be using.

* Disable XFS Service - To disable the XFS Service, comment out the following line in `/etc/inetd.conf` (remember to restart `inetd` after making this change)

`fs stream tcp wait nobody /usr/openwin/lib/fs.auto fs`

PROBLEM: Potential buffer overflow in the X Font Server (xfs)
IMPACT: Potential unauthorized access, denial of service.
PLATFORM: HP 9000 Series 700 and 800 running HP-UX 10.10, 10.20,
10.24, 11.00, 11.04, 11.11, and 11.22
SOLUTION: Until patches are available manually install the

MANUAL ACTIONS: Yes - NonUpdate
Install the appropriate fixed xfs.
AVAILABILITY: This bulletin will be updated when patches are
available.
------------------------------------------------------------------
A. Background
CERT Advisory CA-2002-34 reports an remotely exploitable
buffer overflow in the X Font Server (xfs). The versions
of xfs supplied with HP-UX 10.10, 10.20, 10.24, 11.00, 11.04,
11.11, and 11.22 are potentially vulnerable.
B. Recommended solution
Until patches are released download and manually install
the appropriate fixed version of xfs:
10.10 xfs.1010
10.20 xfs.1020
10.24 xfs.1020
11.00 xfs.1100
11.04 xfs.1100
11.11 xfs.1111
11.22 xfs.1111
`

Download the appropriate files from:
System: hprc.external.hp.com (192.170.19.51) Login: xfs Password: xfs1
FTP Access: ``<ftp://xfs:[email protected]/>`` or: ``<ftp://xfs:[email protected]/>``

` Note: There is an ftp defect in IE5 that may result in
a browser hang. To work around this:

Select Tools -> Internet Options -> Advanced
Un-check the option: [ ] Enable folder view for FTP sites.
`

The files are:
xfs.1010 xfs.1020 xfs.1100 xfs.1111

The cksum output:

The md5 output:
MD5 (xfs.1010) = ac33c55d5242aadd48fb7485bacea12b MD5 (xfs.1020) = 8ca2515aeaf6a6838291bc96ad5b41b2 MD5 (xfs.1100) = 159c5547d0efd51d12e79c7a35c514c4 MD5 (xfs.1111) = e0896eab16747df27d7c2262041a66c0
Note: The md5 source is available in HPSBUX9408-016.

Set "umask 022" and copy the appropriate files to a secure directory, for example /. Then:
1. Save the original xfs.
cp /usr/bin/X11/xfs /usr/bin/X11/xfs.orig
2. Determine if xfs is running:
ps -ef | grep xfs
3. Stop xfs if it is running.
/sbin/rc2.d/S620xfs stop
4. Install the appropriate fixed xfs.
cp /xfs.1010 /usr/bin/X11/xfs # for 10.10 or cp /xfs.1020 /usr/bin/X11/xfs # for 10.20 and 10.24 or cp /xfs.1100 /usr/bin/X11/xfs # for 11.00 and 11.04 or cp /xfs.1111 /usr/bin/X11/xfs # for 11.11 and 11.22
5. If xfs had been stopped in step 3, restart it.
/sbin/rc2.d/S620xfs start

`Title : Buffer Overflow Vulnerability in X Font Server
Number : 20021202-01-I
Date : December 4, 2002
Reference: CERT CA-2002-34, VU#312313
Reference: ISS X-Force Alert #21541
Reference: CVE CAN-2002-1317
Fixed in : IRIX 6.5.14

- -----------------------

— Issue Specifics —

It’s been reported that there is a buffer overflow vulnerability in the
X font server used in IRIX versions prior to 6.5.14. It was discovered,
as part of the non-security related X11 updates done to IRIX 6.5.14,
this vulnerability was fixed.
See the following URLs for additional details:
<http://www.cert.org/advisories/CA-2002-34.html>
<http://www.kb.cert.org/vuls/id/312313>
<http://bvlive01.iss.net/issEn/delivery/xforce/alertdetail.jsp?oid=21541>
CERT assigned the following CVE candidates to this vulnerability:
<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-1317>
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.
This issue has been corrected in IRIX 6.5.14 and later versions.
`

`- --------------

— Impact —

The /usr/bin/X11/xfs binary is installed by default on IRIX 6.5 systems as
part of x_eoe.sw.Server.
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 6.5.16f
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.
This vulnerability can be exploited by a remote user (no account on the
local machine is required), and can result in the remote user gaining root
access.
`

`- ----------------------------

— Temporary Workaround —

SGI understands that there are times when upgrading the operating system or
installing patches are inconvenient or not possible. In those instances, we
recommend the following workaround:
# chkconfig fontserver off
# /etc/init.d/fontserver stop
Of course, you will no longer have the services of the font server available
after doing this.
SGI recommends upgrading to IRIX 6.5.14 or later as a permanent fix for this
problem.
`

`- ----------------

— Solution —

SGI has not provided patches for this vulnerability. Our recommendation is
to upgrade to IRIX 6.5.14 or later.
