    icu vulnerability
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 11.10
    - Ubuntu 11.04
    - Ubuntu 10.10
    - Ubuntu 10.04 LTS
    ICU could be made to crash or run programs as your login if it
    opened specially crafted data.
    Software Description:
    - icu: International Components for Unicode library
    It was discovered that ICU did not properly handle invalid locale data
    during Unicode conversion. 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 11.10:
      libicu44                        4.4.2-2ubuntu0.11.10.1
    Ubuntu 11.04:
      libicu44                        4.4.2-2ubuntu0.11.04.1
    Ubuntu 10.10:
      libicu42                        4.2.1-3ubuntu0.10.10.1
    Ubuntu 10.04 LTS:
      libicu42                        4.2.1-3ubuntu0.10.04.1
    In general, a standard system update will make all the necessary changes.
