<p>International Components for Unicode (ICU) is a set of C/C++ and Java
libraries providing Unicode and Globalization support for software
<p>An error in the _canonicalize() function in uloc.cpp could cause a
stack-based buffer overflow.
<impact type="normal">
<p>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.
<p>There is no known workaround at this time.</p>
<p>All ICU users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=dev-libs/icu-49.1.1-r1"
