icu vulnerabilities
==========================================================================

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

- Ubuntu 17.04
- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in ICU.

Software Description:
- icu: International Components for Unicode library

Details:

It was discovered that ICU incorrectly handled certain memory operations
when processing data. If an application using ICU processed crafted data,
a remote attacker could possibly cause it to crash or potentially execute
arbitrary code with the privileges of the user invoking the program.

Update instructions:

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

Ubuntu 17.04:
libicu57 57.1-5ubuntu0.1

Ubuntu 16.10:
libicu57 57.1-4ubuntu0.2

Ubuntu 16.04 LTS:
libicu55 55.1-7ubuntu0.2

Ubuntu 14.04 LTS:
libicu52 52.1-3ubuntu0.6

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