fex - security update

• [CVE-2014-3875]

When inserting encoded newline characters into a request to rup,
additional HTTP headers can be injected into the reply, as well
as new HTML code on the top of the website.

• [CVE-2014-3876]
  The parameter akey is reflected unfiltered as part of the HTML
  page. Some characters are forbidden in the GET parameter due
  to filtering of the URL, but this can be circumvented by using
  a POST parameter.
  Nevertheless, this issue is exploitable via the GET parameter
  alone, with some user interaction.
• [CVE-2014-3877]
  The parameter addto is reflected only slightly filtered back to
  the user as part of the HTML page. Some characters are forbidden
  in the GET parameter due to filtering of the URL, but this can
  be circumvented by using a POST parameter. Nevertheless, this
  issue is exploitable via the GET parameter alone, with some user
  interaction.

For Debian 6 Squeeze, these issues have been fixed in fex version 20100208+debian1-1+squeeze4
