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" References ========== [ 1 ] CVE-2008-0171 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0171 [ 2 ] CVE-2008-0172 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0172 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200802-08.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
