Bug description:Invalid path SNI_server_certs causes segfault
Description:
------------
If the SNI_server_certs stream ssl option contains an invalid path, it
causes segfault after the client connects. It is because the
initializing loop is jumped off when error happens and keeps the
sni_certs unitialized which causes later segfault when they are freed.
Test script:
---------------
$flags = STREAM_SERVER_BIND|STREAM_SERVER_LISTEN;
$ctx = stream_context_create(['ssl' => [
'local_cert' => __DIR__ . '/domain1.pem',
'SNI_server_certs' => [
"domain1.com" => __DIR__ . "/sni_server_domain1.pem",
"domain2.com" => __DIR__ . "/unknown",
]
]]);
$server = stream_socket_server('tls://127.0.0.1:64321', $errno, $errstr,
$flags, $ctx);
for ($i=0; $i < 3; $i++) {
@stream_socket_accept($server, 3);
}
Expected result:
----------------
Warning: failed setting local cert chain file `%s'; file not found
Actual result:
--------------
segfault
