PHP Bug Type: OpenSSL related
Bug description: openssl_pkcs7_encrypt segmentation fault
Description:
------------
When using openssl_pkcs7_encrypt, Apache seg faults. I can perform the
same smime related function with openssl alone but not in PHP.
I have tried different sized messages, different headers, different certs,
etc and it always seg faults.
Reproduce code:
---------------
$headers_array = explode("\r\n", $header);
$infilename = tempnam("/tmp/", "smime-in-");
$outfilename = tempnam("/tmp/", "smime-out-");
unlink($outfilename);
$fp2 = fopen($infilename, "w");
fwrite($fp2, $mimeData.substr($message, strpos($message,
"\r\n\r\n") + 2)."\r\n");
fclose($fp2);
$cert = $cert_array[0];
$encrypted = openssl_pkcs7_encrypt($infilename, $outfilename,
$cert, $headers_array, 0);
Expected result:
----------------
smime encrypted data to be written to $outfilename.
Actual result:
--------------
When ran in a browser the page stays the same and doesn't move on to the
page the code is being ran on and I get "child pid 5314 exit signal
Segmentation fault (11)" in the Apache error log. When ran from the
command line I get a sefmentation fault and a core dumped.
Here is the backtrace. Doesn't seem to be much there.
