Description: A vulnerability was reported in Bugzilla. A remote user can conduct cross-site scripting attacks.
The software does not properly filter HTML code from user-supplied input before displaying the input. A remote user can create a
specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's
browser. The code will originate from the site running the Bugzilla software and will run in the security context of that site.
As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with
the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the
target user.
The "Format for Printing" view of a bug and the "Long Format" of a bug list display modes are affected.
