OsX: phantomjs binary is without a __PAGEZERO segment

[aanno]

As I observed when using phantomjs with the kernel hardening SUIDguard, the binary is missing a __PAGEZERO segment (details: sektioneins/SUIDGuard#6).

It is likely that security constains will disallow this soon (details (in german): http://www.heise.de/mac-and-i/meldung/Wieder-Root-Luecke-in-OS-X-Yosemite-inklusive-10-10-5-2780509.html).

It would be great to solve this.

Sorry for not getting back to you about this sooner.

When built from the current development sources, on OSX 10.9, using a current version of XCode, the phantomjs binary does contain a __PAGEZERO segment. We know that the official binary on the website is out of date and doesn't work reliably on all OSX versions that are supposed to be supported - please be patient, it's on our list. In the meantime, you are encouraged to build it yourself - it's not terribly difficult, although it is slow and requires a great deal of RAM.

Hmm, I still don't see the segment in our binary:

$ otool -IV ./phantomjs | grep PAGEZERO

Is there any other way to verify this?

It's there. Try: otool -l ./phantomjs | grep PAGEZERO

Perfect 👍 Now we can safely resolve this issue.
