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

Class:       Information leak
Affected:    2.17.5 is the only version affected.
Description: A new feature was introduced in version 2.17.5 which allows
             remote websites to build tooltips and other dynamically
             generated data using current bug information retrieved from
             Bugzilla.  A security lapse in the initial implementation
             of this feature allows the remote site to obtain that
             information from Bugzilla using the privileges of the
             client user.
