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

- Ubuntu 15.04
- Ubuntu 14.10
- Ubuntu 14.04 LTS

Summary:

ICU could be made to crash or run programs as your login if it processed
specially crafted data.

Software Description:
- icu: International Components for Unicode library

Details:

Pedro Ribeiro discovered that ICU incorrectly handled certain memory
operations when processing data. If an application using ICU processed
crafted data, an attacker could 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 15.04:
  libicu52                        52.1-8ubuntu0.1

Ubuntu 14.10:
  libicu52                        52.1-6ubuntu0.3

Ubuntu 14.04 LTS:
  libicu52                        52.1-3ubuntu0.3

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