PHP 4.0.0 through 4.4.6 and 5.0.0 through 5.2.1 allows context-dependent attackers to read arbitrary memory locations via an interruption that triggers a user space error handler that changes a parameter to an arbitrary pointer, as demonstrated via the iptcembed function, which calls certain convert_to_* functions with its input parameters

Remediation
Red Hat statement
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.
