WebAuth 4.4.3 Announcement

The ITS WebAuth team is pleased to announce Stanford WebAuth 4.4.3. This is a bug fix release for all components of WebAuth.

For documentation and downloads of WebAuth 4.4.3, see:

<http://webauth.stanford.edu/>

New Debian packages built against Apache 2.4 have been uploaded to Debian experimental.

The user-visible changes in this release are:

  • Fix a coding error in the WebAuthTrustAuthzIdentity directive parsing that also enabled WebAuthDoLogout for the same scope.

  • If the user asserts an authorization identity equal to their authentication identity, discard the authorization identity in the WebKDC login process and continue as if they did not choose an authorization identity. This fixes a previously fatal error when the user selects their default identity in WebLogin (if, for example, they are trying to undo a previous choice of authorization identity). Thanks to Benjamin Coddington for the report.

  • Remove an arbitrary limit in mod_webauthldap on the number of values from a multivalued LDAP attribute that are put in the environment. Previous versions would only add the first 127 values, but there are some cases where one may want to see more values than that. This opens the possibility of overflowing the allowed size of the environment, but the maximum environment size is quite large on most modern operating systems.

  • Fix syntax error in the replay condition in the default WebLogin error template.

  • Ignore empty app cookies rather than logging an error saying they cannot be parsed. These are created internally by mod_webauth to remove expired cookies and may be seen by subqueries.

  • Log a more informative message in mod_webauth when the user's app cookie has expired instead of a generic parse error and downgrade it to the info level from error.

  • Stop logging the raw binary app token in mod_webauth when it cannot be decoded. This was old debugging code left over from fixing a problem in a much earlier version of WebAuth.

  • Fix some incorrect error handling caught by clang --analyze. None of these were serious, but they could have resulted in strange error messages or a NULL pointer dereference in very rare situations.
