CVE-2011-4838
JRuby before 1.6.5.1 computes hash values without restricting the
ability to trigger hash collisions predictably, which allows
context-dependent attackers to cause a denial of service (CPU
consumption) via crafted input to an application that maintains a hash
table.

CVE-2011-4815
Ruby (aka CRuby) before 1.8.7-p357 computes hash values without
restricting the ability to trigger hash collisions predictably, which
allows context-dependent attackers to cause a denial of service (CPU
consumption) via crafted input to an application that maintains a hash
table.

CVE-2011-5036
Rack before 1.1.3, 1.2.x before 1.2.5, and 1.3.x before 1.3.6 computes
hash values for form parameters without restricting the ability to
trigger hash collisions predictably, which allows remote attackers to
cause a denial of service (CPU consumption) by sending many crafted
parameters.

CVE-2011-5037
Google V8 computes hash values for form parameters without restricting
the ability to trigger hash collisions predictably, which allows
remote attackers to cause a denial of service (CPU consumption) by
sending many crafted parameters, as demonstrated by attacks against
Node.js.");
