Mandriva Linux Security Advisory MDVSA-2015:129 http://www.mandriva.com/en/support/security/ _______________________________________________________________________
Package : ruby Date : March 29, 2015 Affected: Business Server 2.0 _______________________________________________________________________
Problem Description:
Updated ruby packages fix security vulnerabilities: Due to unrestricted entity expansion, when reading text nodes from an XML document, the REXML parser in Ruby can be coerced into allocating extremely large string objects which can consume all of the memory on a machine, causing a denial of service (CVE-2014-8080). Will Wood discovered that Ruby incorrectly handled the encodes() function. An attacker could possibly use this issue to cause Ruby to crash, resulting in a denial of service, or possibly execute arbitrary code. The default compiler options for affected releases should reduce the vulnerability to a denial of service (CVE-2014-4975). Due to an incomplete fix for CVE-2014-8080, 100% CPU utilization can occur as a result of recursive expansion with an empty String. When reading text nodes from an XML document, the REXML parser in Ruby can be coerced into allocating extremely large string objects which can consume all of the memory on a machine, causing a denial of service (CVE-2014-8090). _______________________________________________________________________
