http://security.gentoo.org/

Severity:	normal
Title:	Boost: Denial of Service
Date:	02/14/2008
Bugs:	#205955
ID:	200802-08

Synopsis

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

Background

Boost is a set of C++ libraries, including the Boost.Regex library to process regular expressions.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-libs/boost	< 1.34.1-r2	>= 1.34.1-r2	All supported architectures

Description

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

A remote attacker could provide specially crafted regular expressions to an application using Boost, resulting in a crash.

Workaround

There is no known workaround at this time.

Resolution

All Boost users should upgrade to the latest version:

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