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

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

- Ubuntu 17.10
- Ubuntu 17.04

- Ubuntu 14.04 LTS

Summary:

curl could be made to crash or run programs if it received specially
crafted network traffic.

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

Details:

Brian Carpenter discovered that curl incorrectly handled IMAP FETCH
response lines. A remote attacker could use this issue to cause curl to
crash, resulting in a denial of service, or possibly execute arbitrary
code.
