Gentoo Linux Security Advisory

Title: International Components for Unicode: User-assisted execution of
arbitrary code
(GLSA 201209-07)
Severity: normal
Exploitable: remote
Date: September 24, 2012
Bug(s): #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: dev-libs/icu
Vulnerable: < 49.1.1-r1
Unaffected: >= 49.1.1-r1
Architectures: 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:
