----------------------------------------------------------------- Source: HEWLETT-PACKARD COMPANY SECURITY BULLETIN: HPSBUX0212-228 Originally issued: 4 December 2002 SSRT2429 Security Vulnerability in xfs ----------------------------------------------------------------- NOTICE: There are no restrictions for distribution of this Bulletin provided that it remains complete and intact.
The information in the following Security Bulletin should be acted upon as soon as possible. Hewlett-Packard Company will not be liable for any consequences to any customer resulting from customer's failure to fully implement instructions in this Security Bulletin as soon as possible.
------------------------------------------------------------------ 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: hprc.external.hp.com/">ftp://xfs:xfs1
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
