SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201203-05 (Rack: Denial of Service)
Rack does not properly randomize hash functions to protect against hash collision attacks.
A remote attacker could send a specially crafted form post, possibly resulting in a Denial of Service condition.
There is no known workaround at this time.
SolutionAll Rack users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-ruby/rack-1.1.3'
