   http://itrc.hp.com
 
For HP-UX B.11.00  -  PHCO_29249 and PHNE_17030
For HP-UX B.11.11  -  PHCO_33215
For HP-UX B.11.23  -  PHCO_32926
 
 
For HP-UX B.11.22 the issue can be worked around by disabling remshd and avoiding the 
use of the telnet -t option.  To disable remshd, comment out all lines in 
/etc/inetd.conf were remshd is mentioned.    The telnetd line in /etc/inetd.conf 
should be edited to remove the -t option if it is present.  After making the changes 
to inetd.conf run "/usr/sbin/inetd -c" or reboot the system.
MANUAL ACTIONS:  Yes - NonUpdate
For HP-UX B.11.22,  disable remshd and avoid the telnet -t option.
 
For  HP-UX B.11.00,  B.11.11, and B11.23, there are no manual actions.
