Synopsis

The remote host is running a download client that is vulnerable to a buffer overflow attack.

Description

The remote host is running cURL, a download client for various protocols. The installed version of cURL is earlier than 7.20.0. Such versions are potentially affected by a buffer overflow vulnerability when downloading compressed files over HTTP and automatically decompressing the file with the 'CURLOPT_ENCODING' option.

Solution

Upgrade to cURL 7.20.0 or later.
