Two vulnerabilities have been reported in Boost, each one possibly resulting in a Denial of Service.
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.
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:
