NVD Description

Note: Versions mentioned in the description apply only to the upstream openjdk-7 package and not the openjdk-7 package as distributed by Ubuntu. See How to fix? for Ubuntu:12.10 relevant fixed versions and status.

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.
