Re: mounting /tmp noexec (was: Campus Computers)


why is this? Surely it is better security to do so?

for example, an insecure cgi script could allow a user to write to /tmp
and get the web server to execute the script. By mounting /tmp noexec,
this problem is potentially prevented (aside from the insecure script).

so surely, if nothing needs to be executed, it is better to mount
