weakness in hash salt generation
Dovecot has routines for password hashing; two of these, crypt_generate and md5_generate, both use sizeof(salt_chars) when reducing a random string to salt. I became suspicious when I noted that all salts generated are composed only of "./01". Unfortunately salt_char is declared static const char * rather than static const char [], and so sizeof(salt_chars) is the size of a pointer.
