I.
A. Background
There are 2 problems with FTP Server (ftpd) on HP-UX.
1. ftpd handling of the SITE EXEC command that allows remote
users to gain root access. This is possible in the default
configuration of ftpd on HP-UX 11.00 ONLY.
2. ftpd does not properly format the parameters to the
setproctitle() function, allowing users to gain root access.
This problem applies to both 11.00 and 10.X.
B. Fixing the problem
All system administrators are encouraged to install our temporary
binary until an official patch is released. The file can be
retrieved to simply replace the original factory supplied binary.
C. Recommended solution
Two temporary ftpd binaries (for HP-UX 11.00 and HP-UX 10.20)
can be found at:
