Boost: Denial of service

Boost: Denial of service Two vulnerabilities have been reported in Boost, each one possibly resulting in a Denial of Service. boost 2008-02-14 2008-02-14 205955 remote 1.34.1-r2 1.34.1-r2

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:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-libs/boost-1.34.1-r2"
