PHP is vulnerable to use-after-free vulnerability. This is because the ext/standard/var_unserializer.re in PHP is prone to a heap use after free while unserializing untrusted data, related to improper use of the hash API for key deletion in a situation with an invalid array size. This could impact the integrity of PHP.
