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

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

- Ubuntu 13.04

Summary:

libcurl could be made to crash or run programs as your login if it received
specially crafted input.

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

Details:

Timo Sirainen discovered that libcurl incorrectly handled memory when
parsing URL encoded strings. An attacker could possibly use this issue to
cause libcurl to crash, leading to a denial of service, or execute
arbitrary code.
