There is a severe security issue with Mac OS X 10.2 Jaguar, which allows
any user of the system to navigate through the entire filesystem, and
possibly overwrite any file. The security issue lies within the 'NetInfo
Manager' application, which is setuid root. Whenever an user runs this
application, the entire appliation is running as root.
Therefore, if the user runs 'NetInfo Manager' and chooses to print the
window content by choosing 'Domain: Print', the Print dialog is running
as root? By choosing to 'Save as PDF', the associated file manager
window is itself running as root, thus allowing the user to navigate all
files on the connected hard disks. Moreover, by creating a filesystem
link to any file of the filesystem, calling the link 'dummy.pdf', and
then saving the PDF over this link, the user is then allowed to
overwrite the contents of any file of the filesystem, including system
files or files owned by other users on the system.
Although this security hole cannot be used to gain priviledged status
with a clean install of Jaguar, it might be possible for a malicious
user to install a custom Print Driver of his choosing, which could, for
exemple, run a copy of Terminal.app as root, thus allowing the attacker
to gain root access.
A similar security issue has already been discovered a few month ago,
where running 'NetInfo Manager' allowed any user to become root while
choosing a program from the Apple menu. Setuid applications have severe
security implications, this should not been forgotten.
Also, note that from all the programs shipped with Jaguar which are
setuid root, NetInfo Manager is the only program which does not 'drop
priviledges'.
I am hoping that a security fix will be available as soon as possible.
For the good of the community, I am not going to divulge this security
issue for a reasonable period of time or until you provide a fix or
publish a technical note about it, whichever comes first. Do not
hesitate to contact me should you need more information about this
problem,

Get more done with the new Google Chrome. A more simple, secure, and faster web browser than ever, with Google's smarts built-in. If you do not specify the -tcl85 flag, McIDAS-X is built using Tcl/Tk version 8.4.2 on Linux and Solaris, and 8.5.9 on Windows and Mac OS X. Version 8.5.9 allows sites with custom GUIs to utilize some new data/time capabilities and is the only version available for Windows and Mac OS X. Users of 8.5.9 may see some problems with scrolling. Mac users are being urged to update to macOS Big Sur 11.3 as at least one threat group is exploiting the zero-day bug to sneak past the operating system's built-in security mechanisms Apple has.
