EPSS 5.12%
Description
The curl_easy_duphandle function in libcurl 7.17.1 through 7.38.0, when running with the CURLOPT_COPYPOSTFIELDS option, does not properly copy HTTP POST data for an easy handle, which triggers an out-of-bounds read that allows remote web servers to read sensitive memory information.
