Mac symlink attack techniques?

[Jon Hart <jhart () spoofed org>]

Greetings,

I'm curious if anyone has some input on this.  I am in a situation where
I am able to perform a symlink attack against a process that runs as
root on a Mac.  The catch is that I can create files that don't exist
and get them be created mode 666 for world writable goodness, but if the
symlink points to a file that already exists all I can do is clobber its
content with garbage.

Clearly, havoc can be made by trashing important files, but I'm looking
for an elegant and quick method for privilege escalation.  Is
/etc/ld.so.conf my only option?

Any input would be appreciated.

Thanks!
