CWE-310  (opens in a new tab)

How to fix?

Upgrade Ubuntu:14.04 jruby to version 1.5.6-5 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream jruby package and not the jruby package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

JRuby computes hash values without properly 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, as demonstrated by a universal multicollision attack against the MurmurHash2 algorithm, a different vulnerability than CVE-2011-4838.
