Gentoo Linux Security Advisory

Title: Boost: Denial of Service (GLSA 200802-08)
Severity: normal
Exploitable: remote
Date: February 14, 2008
Bug(s): #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: dev-libs/boost
Vulnerable: < 1.34.1-r2
Unaffected: >= 1.34.1-r2
Architectures: 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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/boost-1.34.1-r2"
