|Gentoo Linux Security Advisory
Title: Rack: Denial of Service (GLSA 201203-05)
Date: March 06, 2012
A hash collision vulnerability in Rack allows remote attackers to
cause a Denial of Service condition.
Rack is a modular Ruby web server interface.
Vulnerable: < 1.1.3
Unaffected: >= 1.1.3
Architectures: All supported architectures
Rack does not properly randomize hash functions to protect against hash
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"
