Severity:	normal
Title:	International Components for Unicode: User-assisted execution of arbitrary code
Date:	09/24/2012
Bugs:	#394201
ID:	201209-07

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	Architecture(s)
dev-libs/icu	< 49.1.1-r1	>= 49.1.1-r1	All supported architectures

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"
