Description

Background

Rack is a modular Ruby web server interface.

Description

Rack does not properly randomize hash functions to protect against hash collision attacks.

Impact

A remote attacker could send a specially crafted form post, possibly resulting in a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All Rack users should upgrade to the latest version:

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