-------------------------+--------------------------------------------------
libssh2 encounter SIGSEGV when null passphrase is passed to
libssh2_userauth_publickey_fromfile while the passed key requires a valid
passphrase.
My application takes these configuration from user,and when passed along
they cause app to crash.
The error is traced to passphrase_cb in openssl.c.
This function does not check for null passphrase and tries to find strlen
causing the segmentation fault.
A simple check such as this would suffice,
passphrase_len = 0;
if(passphrase != NULL)
passphrase_len = strlen(passphrase);
