1.  Gentoo Linux Security Advisory

Version Information

Advisory Reference GLSA 201209-07 / icu
Release Date September 24, 2012
Latest Revision September 24, 2012: 1
Impact normal
Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)
dev-libs/icu < 49.1.1-r1 >= 49.1.1-r1 All supported architectures

Related bugreports: #394201


A buffer overflow in International Components for Unicode could result in execution of arbitrary code or Denial of Service.

2.  Impact Information


International Components for Unicode (ICU) is a set of C/C++ and Java libraries providing Unicode and Globalization support for software applications.


An error in the _canonicalize() function in uloc.cpp could cause a stack-based buffer overflow.


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.

3.  Resolution Information


There is no known workaround at this time.


All ICU users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-libs/icu-49.1.1-r1"
