Updated curl packages fix security vulnerability:

Symeon Paraschoudis discovered that the curl_easy_duphandle() function
in cURL has a bug that can lead to libcurl eventually sending off
sensitive data that was not intended for sending, while performing
a HTTP POST operation. This bug requires CURLOPT_COPYPOSTFIELDS and
curl_easy_duphandle() to be used in that order, and then the duplicate
handle must be used to perform the HTTP POST. The curl command line
tool is not affected by this problem as it does not use this sequence
(CVE-2014-3707).
