Tavis Ormandy and Will Drewry from the Google Security Team reported a
failed assertion in file regex/v4/perl_matcher_non_recursive.hpp
(CVE-2008-0171) and a NULL pointer dereference in function
get_repeat_type() file basic_regex_creator.hpp (CVE-2008-0172) when
processing regular expressions.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could provide specially crafted regular expressions
to an application using Boost, resulting in a crash.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Boost users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/boost-1.34.1-r2"</code>
</resolution>
