libcurl.so is vulnerable to Cookie Injection. The vulnerability is due to a lack of proper validation in the curl_easy_duphandle function in easy.c when setting the filename of the cookie to “none”, In case the parent handle didn’t specify a file. This flaw allows an attacker to insert cookies into a running program using libcurl by placing a malicious “none” file in the application’s directory.
