Use-after-free vulnerability in the process_nested_data function in
ext/standard/var_unserializer.re in PHP before 5.4.36, 5.5.x before 5.5.20,
and 5.6.x before 5.6.4 allows remote attackers to execute arbitrary code
via a crafted unserialize call that leverages improper handling of
duplicate keys within the serialized properties of an object, a different
vulnerability than CVE-2004-1019.
