==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

– Ubuntu 14.10
– Ubuntu 14.04 LTS

– Ubuntu 10.04 LTS

Summary:

curl could be tricked into adding arbitrary requests when following certain
URLs.

Software Description:
– curl: HTTP, HTTPS, and FTP client and client libraries

Details:

Andrey Labunets discovered that curl incorrectly handled certain URLs when
using a proxy server. If a user or automated system were tricked into using
a specially crafted URL, an attacker could possibly use this issue to
inject arbitrary HTTP requests.
