Synopsis
========

Multiple vulnerabilities have been found in ICU, the worst of which
could allow remote code execution.

Background
==========

ICU is a mature, widely used set of C/C++ and Java libraries providing
Unicode and Globalization support for software applications.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-libs/icu                < 58.2-r1                 >= 58.2-r1 

Description
===========

Multiple vulnerabilities have been discovered in ICU. Please review the
referenced CVE identifiers for details.

Impact
======

A remote attacker could possibly execute arbitrary code with the
privileges of the process or cause a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All ICU users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-libs/icu-58.2-r1"

Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these
packages.
