  when handling image form fields (CVE-2009-3236).

* Martin Geisler and David Wharton reported that an error exists in
  the MIME viewer library when viewing unknown text parts and the
  preferences system in services/prefs.php when handling number
  preferences (CVE-2009-3237).

Impact

A remote authenticated attacker could exploit these vulnerabilities to
overwrite arbitrary files on the server, provided that the user has
