Rack: Denial of service A hash collision vulnerability in Rack allows remote attackers to cause a Denial of Service condition. rack 2012-03-06 2012-03-06 396455 remote 1.1.3 1.1.3

Rack is a modular Ruby web server interface.

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.

All Rack users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=dev-ruby/rack-1.1.3"
