CVE-2011-4815

Published Dec 30, 2011 ruby-lang CWE-20

Overview

CVE-2011-4815 is a known-severity vulnerability affecting ruby-lang ruby. It was published on December 30, 2011.

Technical 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.

Remediation

Check the references section for vendor advisories and patches from ruby-lang. Update ruby to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
