GLSA-200802-08 : Boost: Denial of Service
Medium Nessus Plugin ID 31110
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200802-08 (Boost: Denial of Service)
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.
SolutionAll Boost users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/boost-1.34.1-r2'
