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

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

Summary:

curl could be made to crash or expose information if it received specially
crafted network traffic.

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

curl to crash, resulting in a denial of service, or possibly obtain
sensitive memory contents.
