Original 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 software
- Ruby = 1.8.7-p334= 1.8.7-p302= 1.8.7-p330≤ 1.8.7-p352= 1.8.7-p299 exact match
