Synopsis
========
A buffer overflow in International Components for Unicode could result
in execution of arbitrary code or Denial of Service.
Background
==========
International Components for Unicode (ICU) is a set of C/C++ and Java
libraries providing Unicode and Globalization support for software
applications.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-libs/icu < 49.1.1-r1 >= 49.1.1-r1
Description
===========
An error in the _canonicalize() function in uloc.cpp could cause a
stack-based buffer overflow.
Impact
======
A remote attacker could entice a user to open a specially crafted
locale representation using an application linked against ICU, possibly
resulting in execution of arbitrary code with the privileges of the
process or 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-49.1.1-r1"
