3.7.1 Security Advisory

Monday, Jul 5th, 2010
Summary
=======

Bugzilla is a Web-based bug-tracking system used by a large number of
software projects. The following security issue has been discovered
in Bugzilla:

* In the 3.7.1 development snapshot, adding bugs using email_in.pl
or the WebServices Bug.create method would not restrict bugs to
Mandatory or Default groups.

All affected installations are encouraged to upgrade as soon as
possible.


Vulnerability Details
=====================

Class:       Unauthorized Access to Confidential Information

Fixed In:    3.7.2
Description: Bugzilla administrators can set certain groups as being
"mandatory" for when a new bug is filed. (That is, bugs
are always restricted to access by those groups.)
Administrators can also set some groups as "Default",
meaning that if the user makes no selection about groups,
the new bug will be restricted to the groups set as
Default. In the unreleased 3.7 code and 3.7.1 development
snapshot, restricting a bug to mandatory or default groups
would not happen when the bug was newly created using the
inbound email interface (email_in.pl) or the "Bug.create"
method in the WebServices interface. This means that these
bugs could be publicly available, when they should have
been restricted to being accessible only to certain
groups.
