    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)

    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
