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
         appropriate fixed version of xfs.

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:xfs1@hprc.external.hp.com/
            or: ftp://xfs:xfs1@192.170.19.51/


      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:


        4146829079 147456 xfs.1010
       2943686322 155648 xfs.1020
       1843422197 163840 xfs.1100
       3420832763 176128 xfs.1111

    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
