Updated php packages fix a security vulnerability

In PHP versions 7.2.x when PHP is processing incoming HTTP cookie values, the cookie names are url-decoded. This may lead to cookies with prefixes like __Host confused with cookies that decode to such prefix, thus leading to an attacker being able to forge cookie which is supposed to be secure. (CVE-2020-7070) These updated packages also fix several bugs: Core: - realpath() erroneously resolves link to link - Stack use-after-scope in define() - getimagesize function silently truncates after a null byte - Memleak when coercing integers to string via variadic argument Fileinfo: finfo_file crash (FILEINFO_MIME) LDAP: Fixed memory leaks. OPCache: opcache.file_cache causes SIGSEGV when custom opcode handlers changed. Standard: Memory leak in str_replace of empty string
