Vulnerability Details

Class:       Unauthorized Bug Change
Versions:    3.1.1 through 3.2.3, 3.3.1 through 3.3.4
Fixed In:    3.2.4, 3.4rc1
Description: Users could, in some situations, confirm bugs even if they
              weren't in the canconfirm group, or set a bug to statuses
              that they normally didn't have access to. (For example,
              bug reporters who had no permissions could set their bug
              to any status, while they are only supposed to be able to
              close their bug.)
