<background>
<p>
libpcre is a library providing functions for Perl-compatible
regular expressions.
</p>
</background>
<description>
<p>
libpcre fails to check certain quantifier values in regular
expressions for sane values.
</p>
</description>
<impact type="high">
<p>
An attacker could possibly exploit this vulnerability to execute
arbitrary code by sending specially crafted regular expressions to
applications making use of the libpcre library.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All libpcre users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/libpcre-6.3&quot;</code>
</resolution>
