========================================================================== Ubuntu Security Notice USN-2412-1 November 20, 2014
ruby1.8, ruby1.9.1, ruby2.0, ruby2.1 vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS
Summary:
Ruby could be made to consume resources.
Software Description: - ruby2.0: Object-oriented scripting language - ruby2.1: Object-oriented scripting language - ruby1.9.1: Object-oriented scripting language - ruby1.8: Object-oriented scripting language
Details:
Tomas Hoger discovered that Ruby incorrectly handled XML entity expansion. An attacker could use this flaw to cause Ruby to consume large amounts of resources, resulting in a denial of service.
