Description
Oracle Java SE before 7 Update 6, and OpenJDK 7 before 7u6 build 12 and 8 before build 39, 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
• oracle jdk (<= 1.7.0)
• oracle jdk 1.7.0
• oracle jre (<= 1.7.0)
• oracle jre 1.7.0
• oracle openjdk (<= 1.7.0)
• oracle openjdk 1.6.0
• oracle openjdk 1.8.0
