How to fix?

Upgrade Ubuntu:12.04 curl to version 7.22.0-3ubuntu4.17 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Ubuntu. See How to fix? for Ubuntu:12.04 relevant fixed versions and status.

The base64 encode function in curl before version 7.51.0 is prone to a buffer being under allocated in 32bit systems if it receives at least 1Gb as input via CURLOPT_USERNAME.
