For affected systems verify that the recommended action has been taken. AFFECTED VERSIONS HP-UX B.11.00 ============= X11.X11-RUN-CL action: remove PHSS_32109 if installed HP-UX B.11.11 ============= X11.X11-RUN-CL ->action: install PHSS_34102 HP-UX B.11.23 ============= X11.X11-RUN-CL action: remove PHSS_31833 if installed HP-UX B.11.23 ============= X11.X11-RUN-CL action: remove PHSS_32366 if installed END AFFECTED VERSIONS RESOLUTION ->For HP-UX B.11.11 ->HP has provided the following patch to resolve the issue for ->B.11.11: ->B.11.11 - PHSS_34102 ->The patch can be downloaded from http://itrc.hp.com ->For HP-UX B.11.00 and B.11.23 Until patches are provided to resolve the issue avoid using the potentially vulnerable versions of /usr/bin/X11/xterm. The following are three methods to replace the potentially vulnerable xterm. 1. One solution is to remove the patches listed in the Background section (above). The patches listed are the only patches containing the potentially vulnerable xterm. 2. An alternative to removing the patches is to use /usr/contrib/bin/X11R5/xterm. For example: cp /usr/bin/X11/xterm /usr/bin/X11/xterm.nosuid chmod 555 /usr/bin/X11/xterm.nosuid cp /usr/contrib/bin/X11R5/xterm /usr/bin/X11/xterm 3. Preliminary xterm Binary Files Preliminary xterm binary files are available to resolve the issue. These binary files are X11R6 replacements for the potentially vulnerable versions of xterm, and they contain the same defect fixes. Customers who do not require the latest xterm may prefer to remove the patches listed above instead. Manual action is required to install the preliminary binary xterm files. To install the preliminary xterm download README.txt and the appropriate xterm file via ftp from hprc.external.hp.com (192.170.19.100). The ftp account is 'xterm', and the password is 'xterm'. Browser ftp access: ftp://xterm:xterm@hprc.external.hp.com/ ftp://xterm:xterm@192.170.19.100/ README.txt contains instructions for installing the preliminary files. cksum: 766557324 1630 README.txt md5 sum: 960cc500dcf9d4c2c72464822bc79c18 README.txt MANUAL ACTIONS: Yes - NonUpdate - ->For HP-UX B.11.00 and B.11.23 Remove the patches listed in the Background section, use /usr/contrib/bin/X11R5/xterm, or install the preliminary xterm files.
