This advisory covers a critical security issue that has recently been
fixed in the Bugzilla code:
* Even with account creation disabled, users can use the WebService to
create an account.
We strongly advise that 2.23.x and 3.0.x users upgrade to 3.0.2
immediately. Users of CVS HEAD or 3.1.1 should upgrade to 3.1.2
immediately. This is critical if you have a "requirelogin" installation
and also have the WebService enabled.
Class: Unauthorized Access
Versions: 2.23.3 and above.
Description: Bugzilla::WebService::User::offer_account_by_email does
not check the "createemailregexp" parameter, and thus
allows users to create accounts who would normally be
denied account creation.
The "emailregexp" parameter is still checked.
If you do not have the SOAP::Lite Perl module installed on
your Bugzilla system, your system is not vulnerable
(because the Bugzilla WebService will not be enabled).
The fix for the security bug mentioned in this advisory is
included in the 3.0.2 and 3.1.2 releases. Upgrading to these
releases will protect installations from possible exploits of this
