Description
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.
Affected configurations
• ruby-lang ruby (<= 1.8.7-p352)
• ruby-lang ruby 1.8.7-p299
• ruby-lang ruby 1.8.7-p302
• ruby-lang ruby 1.8.7-p330
• ruby-lang ruby 1.8.7-p334
