|Gentoo Linux Security Advisory
Title: Boost: Denial of Service (GLSA 200802-08)
Date: February 14, 2008
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.
Vulnerable: < 1.34.1-r2
Unaffected: >= 1.34.1-r2
Architectures: All supported architectures
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"
