Bug description: crash when IV is not set
I'm running FreeBSD 4.7 with libmcrypt 2.5.3.
There seems to be a bug in libmcrypt, the crash occurs if you call
mcrypt_generic(), but without valid IV. Here's a short script:
$td = mcrypt_module_open ('des', '', 'cbc', '');
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size ($td), MCRYPT_RAND);
mcrypt_generic_init ($td, substr($nthash, 0, 7));
$res = mcrypt_generic ($td, $challenge);
changing:
mcrypt_generic_init ($td, substr($nthash, 0, 7));
to:
mcrypt_generic_init ($td, substr($nthash, 0, 7), $iv);
solves the problem :-)
