I've just released crypt_blowfish 1.2: http://www.openwall.com/crypt/ To provide for better upgrade strategies from pre-1.1 versions of crypt_blowfish with the sign extension bug (documented previously), this version adds support for the "$2y$" prefix (which guarantees correct handling of both 7- and 8-bit characters as in OpenBSD's "$2a$") and a countermeasure to avoid one-correct to many-buggy hash collisions with the "$2a$" prefix. Other changes include improvements to the "make check" tests and to the runtime quick self-test, addition of a patch for glibc 2.13 and 2.14, and documentation updates. I'd like to thank Ludwig Nussel of SUSE for his helpful feedback on development snapshots leading to this release. At the same time, I've also released a new version of tcb - implementation of our alternative password shadowing scheme. The only change in tcb 1.1 since the previous release is that it will now use the new "$2y$" hash encoding prefix by default, instead of "$2a$": http://www.openwall.com/tcb/ http://www.openwall.com/tcb/ChangeLog Obviously, both of these updates are already in Owl-current, along with relevant changes to the pam and shadow-utils packages. The CHANGES-current entry on the glibc/crypt_blowfish fix has been revised accordingly: http://www.openwall.com/Owl/CHANGES-current.shtml Besides the source code updates, currently available are binary builds of the updated Owl-current packages for i686. Builds for x86_64 and similar changes in Owl 3.0-stable will be made available later. Alexander
