EXPECTED:
If you run test.php (attached ) in command line or as Apache module the
expected output is binary data smaller than 40byte.
BUG:
On my system it outputs 32kbyte, and contains memory dump, PHP source code, PHP
variable values etc.
It looks like similar to a buffer overrun/flow.
I've downloaded PHP5.3.10 source code. Could the following cause it?
php5-5.3.10/ext/openssl/openssl.c line 4716:
if (data_len > 0) {
EVP_EncryptUpdate(&cipher_ctx, outbuf, &i, (unsigned char *)data, data_len);
}
If data IS nothing (empty), it does not call EVP_EncryptUpdate()
function.
