Comment 1 Vasyl Kaigorodov 2015-05-20 14:12:09 UTC 
Created php tracking bugs for this issue:

Affects: fedora-all [bug 1223447]
Comment 2 Tomas Hoger 2015-05-21 20:59:31 UTC 
I noted CVE-2006-7243 (see bug 662707) regressions in PHP 5.4+ for the following functions in the upstream bug report:

- set_include_path()
- tempnam() - second argument only
- rmdir()
- readlink()

readlink() was already fixed in 5.4.40 / 5.5.24 / 5.6.8, see bug 1213407 comment 5.

Linked upstream commit includes additional fixes for issue not mentioned in the upstream bug report 69418.

- pcntl_exec() - tracked via separate bug 1223422 / CVE-2015-4026
- opendir() / dir()
- chroot()

These additional changes are not 5.4+ regressions.
