Title: Boost: Denial of Service
Date: February 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
-------------------------------------------------------------------
1 dev-libs/boost < 1.34.1-r2 >= 1.34.1-r2
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"
