[OATH-Toolkit-help] OATH Toolkit 2.4.1

[Simon Josefsson]

This is a security bugfix for the 2.4.x branch, see below for details.

I have had health issues since late last year -- see
http://blog.josefsson.org/ -- but I hope to return to reviewing Fabian's
OCRA patches so we can finally get them released.

Happy hacking,
Simon

** liboath: Fix usersfile bug that caused it to update the wrong line.
When an usersfile contain multiple lines for the same user but with an
unparseable token type (e.g., HOTP vs TOTP), the code would update the
wrong line of the file.  Since the then updated line could be a
commented out line, this can lead to the same OTP being accepted
multiple times which is a security vulnerability.  Reported by Bas van
Schaik <address@hidden> and patch provided by Ilkka Virta
<address@hidden>.  CVE-2013-7322

The OATH Toolkit makes it easy to build one-time password
authentication systems.  It contains shared libraries, command line
tools and a PAM module.  Supported technologies include the
event-based HOTP algorithm (RFC4226) and the time-based TOTP algorithm
(RFC6238).  OATH stands for Open AuTHentication, which is the
organization that specify the algorithms.  For managing secret key
files, the Portable Symmetric Key Container (PSKC) format described in
RFC6030 is supported.

The components included in the package is:

  * liboath: A shared and static C library for OATH handling.

  * oathtool: A command line tool for generating and validating OTPs.

  * pam_oath: A PAM module for pluggable login authentication for OATH.

  * libpskc: A shared and static C library for PSKC handling.

  * pskctool: A command line tool for manipulating PSKC data.
