libcurl.so is vulnerable to Use After Free. The vulnerability is due to improper freeing of an easy handle within the Curl_close() function. The application frees the struct without assigning it to a null pointer. The usage of previously freed memory could lead to data corruption or lead to a crash if invalid data is entered.
