icu vulnerability
==========================================================================

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

- Ubuntu 17.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

ICU could be made to crash if it received specially crafted input.

Software Description:
- icu: International Components for Unicode library

Details:

It was discovered that ICU incorrectly handled certain calendars. If an
application using ICU processed crafted data, a remote attacker could
possibly cause it to crash, leading to a denial of service.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 17.10:
libicu57 57.1-6ubuntu0.3

Ubuntu 16.04 LTS:
libicu55 55.1-7ubuntu0.4

Ubuntu 14.04 LTS:
libicu52 52.1-3ubuntu0.8

In general, a standard system update will make all the necessary changes.
