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 security vulnerability in sendmail IMPACT: Potential unauthorized Privileged Access, Potential Denial of Service (DoS). PLATFORM: HP 9000 Series 700/800 Servers running HP-UX B.10.10, B.10.20, B.11.00, B.11.04(VVOS), B.11.11, and B.11.22. SOLUTION: Download and install the appropriate files or the HPSecurityBul253.depot. The sendmail files and HPSecurityBul253.depot referenced in HPSBUX0304-253 also address the issues documented in HPSBUX0302-246. If the sendmail files or HPSecurityBul253.depot from HPSBUX0304-253 are installed, it is not necessary to install the sendmail files or HPSecurityBul246.depot from HPSBUX0302-246. If both sets of sendmail files, or both depots, are installed, the sendmail files or HPSecurityBul253.depot from HPSBUX0304-253 must be installed *AFTER* the sendmail files or HPSecurityBul246.depot from HP HPSBUX0302-246 in order to ensure all issues are addressed. MANUAL ACTIONS: Yes - NonUpdate Download and install the appropriate sendmail file, depot, or preliminary patch. AVAILABILITY: Fixes are available for B.10.10, B.10.20, B.11.00, B.11.04(VVOS), B.11.11, and B.11.22. CHANGE SUMMARY: Rev.01 - Added fix for B.11.22. Added HPSecurityBul253.depot. CHANGE SUMMARY: Rev.02 - Corrected filename: /usr/newconfig/etc/mail/sendmail.cf Added sendmail.886.10.10.r1. Rev.03 - New HPSecurityBul253.depot containing sendmail.886.10.10.r1. Rev.04 - Added early release patches for B.11.00 and B.11.11. Rev.05 - Added pre-release sendmail-8.11.1 web upgrades for B.11.00 and B.11.11. Rev.06 - Added pre-release sendmail-8.11.1 patch for B.11.22. Added pre-release sendmail-8.9.3 patch for B.10.20. PHNE_26304 and PHNE_28761 for sendmail 8.9.3 contain the wrong man pages. Changed to uniform revision notation (e.g. 11.00 -> B.11.00) to match the "uname -a" output. ----------------------------------------------------------------- A. Background A potential security vulnerability with sendmail has been reported in HP-UX. This potential vulnerability may result in unauthorized Privileged Access or a Denial of Service (DoS). This potential vulnerability may be exploited remotely. This is the vulnerability reported in CERT/CC CA-2003-12. Note: In order to provide fixes as soon as possible manually installed files are being provided initially. A depot and patches containing these files will be provided as soon as they can be created. A depot (HPSecurityBul253.depot) is now available. Note: This problem also affects: HP Tru64 UNIX/TruCluster Server V4.x and V5.x HP Tru64 UNIX Engineering continues to work this issue at the highest priority. As solution information becomes available HP will provide notice of the availability of any necessary patches through standard security bulletin announcements and be available from your normal HP Services support channel. The HP Tru64 bulletin will be posted to the customer support website within 24 hours of release to - http://thenew.hp.com/country/us/eng/support.html or www.hp.com Use the SEARCH IN feature box, enter SSRT in the search window or use a specific SSRT # (example: SSRT3531) HP ProLiant Servers If running Open Source Sendmail, refer to the following Sendmail Consortium URL for patch details or upgrades: http://www.sendmail.org As more information becomes available HP will provide notice of the availability of any necessary patches through standard security bulletin announcements and be available from your normal HP Services support channel. NOT VULNERABLE: HP NonStop Servers HP OpenVMS. B. Recommended solution **REVISED 06** Currently there are several ways to install solutions depending on the version of HP-UX and the version of sendmail installed: -> HP-UX B.11.22 sendmail 8.11.1 -> A pre-release patch is available from the ftp site. -> Details are below. HP-UX B.11.00 and B.11.11 sendmail 8.11.1 A pre-release web upgrade is available from the ftp site. Details are below. HP-UX B.11.00 and B.11.11 sendmail 8.9.3 A preliminary patch a available from a temporary ftp site. Details are below. -> HP-UX B.10.20 sendmail 8.9.3 -> A pre-release patch is available from the ftp site. -> Details are below. All versions (including those mentioned above) - A depot is available from a temporary ftp site. Details are below. All versions (including those mentioned above) - Individual files are available from a temporary ftp site. Details are below. The files are included in the depot. We recommend using the depot rather than manually installing individual files. Note: It is recommended that an available preliminary patch or pre-release web upgrade be installed rather than the depot. However, the depot contains all the available fixes and will automatically install the correct version. If there are a variety of HP-UX versions to be fixed the depot may prove easier to implement than the preliminary patches or the pre-release web upgrades. Note: The fixes mentioned here include the fix for for HPSBUX0302-246. The files are named to be consistent with the names used in HPSBUX0302-246. For example, HPSBUX0302-246 provided sendmail.811.11.11.r1. This bulletin provides sendmail.811.11.11.r2. All versions of sendmail provided by HP on HP-UX 10.X and 11.X are vulnerable unless one of the fixes described below has been installed. Note: All the files mentioned for download below are available from the following ftp site: System: hprc.external.hp.com (192.170.19.51) Login: sendmail Password: sendmail FTP Access: ftp://sendmail:sendmail@hprc.external.hp.com/ or: ftp://sendmail:sendmail@192.170.19.51/ or: ftp hprc.external.hp.com 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 **REVISED 06** -> ================================================== -> Note: A preliminary patch is available for -> sendmail 8.11.1 on B.11.22. -> ================================================== -> To fix the problem on B.11.22 for -> sendmail 8.11.1 with a preliminary patch: -> 1.

Install the appropriate file as follows: Copy the appropriate sendmail file to a protected directory such as /usr/sbin. If you are running sendmail 8.9.3 also copy the appropriate killsm file to a protected directory such as /usr/sbin. Login as root and run killsm: killsm Verify the sendmail daemon is not running: ps -ef | grep sendmail If you are running the 8.9.3 version of sendmail replace killsm as follows: cd /usr/sbin cp killsm killsm.orig cp killrm.893.10.20 killsm OR cp killrm.893.11.00 killsm OR cp killrm.893.11.11 killsm If you are running B.11.22: cd /usr/sbin cp killsm killsm.orig cp killrm.811.11.22 killsm For all versions of sendmail, make a backup copy of the existing sendmail: cd /usr/sbin cp sendmail sendmail.original Note the permissions for reference: ls -lia /usr/sbin/sendmail Install the new sendmail: cp sendmail.xxx.yy.zz.rn sendmail For example, on B.11.11: cp sendmail.811.11.11.r2 sendmail Restart sendmail. If you were running sendmail before the killsm command above, you can now restart it with the following command (for HP-UX, not VVOS): /sbin/init.d/sendmail start Note: Do not execute the command above for VVOS B.11.04 The command runs sendmail as a daemon, which is not supported by VVOS (Virtual Vault Operating System).
