A password containing a character with the high bit set was misprocessed on machines where char is signed (which is most). This could cause the preceding one to three characters to fail to affect the hashed result, thus weakening the password. The result was also unportable, and failed to match some other blowfish implementations such as OpenBSD's. Since the fix changes the output for such passwords, upstream chose to provide a compatibility hack: password salts beginning with $2x$ (instead of the usual $2a$ for blowfish) are intentionally processed "wrong" to give the same hash as before. Stored password hashes can thus be modified if necessary to still match, though it'd be better to change any affected passwords. In passing, sync a couple other upstream changes that marginally improve performance and/or tighten error checking. Back-patch to all supported branches. Since this issue is already public, no reason not to commit the fix ASAP.

|
|
*
|
|
* This code comes from John the Ripper password cracker, with reentrant
|
|
* and crypt(3) interfaces added, but optimizations specific to password
|
|
* cracking removed.
|
|
*
|
|
* Written by Solar Designer <solar at openwall.com> in 1998-2002 and
|
|
* placed in the public domain.
|
|
*
|
|
* There's absolutely no warranty.
|
|
*
|
|
* It is my intent that you should be able to use this on your system,
|
|
* as a part of a software package, or anywhere else to improve security,
|
|
* ensure compatibility, or for any other purpose. I would appreciate
|
|
* it if you give credit where it is due and keep your modifications in
|
|
* the public domain as well, but I don't require that in order to let
|
|
* you place this code and any modifications you make under a license
|
|
* of your choice.
|
|
*
|
|
* This implementation is compatible with OpenBSD bcrypt.c (version 2a)
|
|
* by Niels Provos <provos at citi.umich.edu>, and uses some of his
|
|
* ideas. The password hashing algorithm was designed by David Mazieres
|
|
* <dm at lcs.mit.edu>.
|
|
*
|
|
* There's a paper on the algorithm that explains its design decisions:
|
|
*
|
|
* http://www.usenix.org/events/usenix99/provos.html
|
|
*
|
|
* Some of the tricks in BF_ROUND might be inspired by Eric Young's
|
|
* Blowfish library (I can't be sure if I would think of something if I
|
|
* hadn't seen his code).
