Description Guilherme de Almeida Suckevicz 2020-04-24 12:59:58 UTC 
If  ``CHARSET_EBCDIC`` is defined (usually, on systems with EBCDIC encoding support), an Out-of-Bounds read can occur using a malformed url-encoded string.

Comment 1 Marco Benatto 2020-04-30 17:13:03 UTC 
Statement:

This affects php running only on platforms using EBCDIC encoding, as versions of Red Hat Enteprise Linux uses ASCII encoding all php versions shipped with it are not vulnerable to this flaw.
