Security update to 4.2.4

- while here switch plist to use @sample

The advisories: PMASA-2014-2 and PMASA-2014-3, have not been published
yet, so there is very little concrete information about what the
security problems are. About all there is comes from the change log,
where the security issues are listed as:

- bug #4464 [security] XSS injection due to unescaped db/table name in navigation hiding
- bug #4465 [security] XSS injection due to unescaped db/table name in recent/favorite tables
