Summary
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.
For the stable distribution (wheezy), this problem has been fixed in
version 7.26.0-1+wheezy11.
For the upcoming stable distribution (jessie), this problem will be
fixed in version 7.38.0-3.
For the unstable distribution (sid), this problem has been fixed in
version 7.38.0-3.
We recommend that you upgrade your curl packages.
