Boost is a set of C++ libraries, including the Boost.Regex library to
process regular expressions.
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.
<impact type="normal">
A remote attacker could provide specially crafted regular expressions
to an application using Boost, resulting in a crash.
There is no known workaround at this time.
All Boost users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/boost-1.34.1-r2&quot;</code>
