Current Description

The array_user_key_compare function in PHP 4.4.6 and earlier, and 5.x up to 5.2.1, makes erroneous calls to zval_dtor, which triggers memory corruption and allows local users to bypass safe_mode and execute arbitrary code via a certain unset operation after array_user_key_compare has been called.

Vendor Statements (disclaimer)

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.
