Official Statement from Red Hat (04/16/2007)
The PHP interpreter does not offer a reliable "sandboxed" security
layer (as found in, say, a JVM) in which untrusted scripts can be run;
any script run by the PHP interpreter must be trusted with the
privileges of the interpreter itself. We therefore do not classify
this issue as security-sensitive since no trust boundary is crossed.
