bugzilla -- multiple vulnerabilities

A Bugzilla Security Advisory reports:

Cross-Site Scripting
When viewing a single bug report, which is the default,
the bug ID is validated and rejected if it is invalid.
But when viewing several bug reports at once, which is
specified by the format=multiple parameter, invalid bug
IDs can go through and are sanitized in the HTML page
itself. But when an invalid page format is passed to the
CGI script, the wrong HTML page is called and data are not
correctly sanitized, which can lead to XSS.
Information Leak
When running a query in debug mode, the generated SQL
query used to collect the data is displayed. The way this
SQL query is built permits the user to determine if some
confidential field value (such as a product name) exists.
This problem only affects Bugzilla 4.0.9 and older. Newer
releases are not affected by this issue.
