Description Robert Schulze 2018-11-21 13:05:04 UTC
Created attachment 199413 [details]
place portmasterfail.txt in ~

When building/upgrading ports via portmaster fails, it will place a list of failed ports in /tmp/portmasterfail.txt.

Not only is this file created world-readable, any local user may create a symlink attack with it.

I recommend placing portmasterfail.txt in $HOME.

with kind regards,
Robert Schulze

URL: https://svnweb.freebsd.org/changeset/ports/524231

  Save the file with instructions how to restart portmaster after a failure
  to non-world-writable directory.

  Save this file in the user's home directory instead of in /tmp to prevent
  a possible sym-link attack against the user.
