Description

Bugzilla contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate the 'real name' field of a user account before returning it to the user when using the YUI AutoComplete widget, which renders textual data as HTML markup. This may allow a user to create a specially crafted URL that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
