2.16.8, 2.18, 2.19.2 Security AdvisoryMay 11, 2005
Summary ======= Bugzilla is a Web-based bug-tracking system, used by a large number of software projects. This advisory covers two security bugs that have recently been discovered and fixed in the Bugzilla code: + In all versions of Bugzilla since at least 2.16, it is possible to guess the name of a hidden product and have Bugzilla confirm that you were correct. + In Bugzilla 2.18 and above, a user's username and password are sometimes exposed in the URL after generating a Report. All Bugzilla installations are advised to upgrade to the latest stable version of Bugzilla, 2.18.1. Development snapshots of 2.19 and above are also vulnerable. If you are using a development snapshot, you should obtain a newer one (2.19.3) or use CVS to update or apply the patches from the specific bugs listed below. Vulnerability Details ===================== Issue 1 ------- Class: Information Leak Versions: 2.10 through 2.18, 2.19.1, 2.19.2 Description: If a user correctly guesses the name of a product that should be invisible to them, they will be specifically informed that they do not have access to it, thus letting them know that the product exists. Also, users can enter bugs into products that are closed for bug entry, if they correctly guess the name of the product.
