-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ 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). _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-8080 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-4975 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-8090 http://advisories.mageia.org/MGASA-2014-0443.html http://advisories.mageia.org/MGASA-2014-0472.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 2/X86_64: 21f6497011d5c12d481fd03fa53302ee mbs2/x86_64/lib64ruby2.0-2.0.0.p598-1.mbs2.x86_64.rpm 577db59ed8804f75ab194a1076523182 mbs2/x86_64/ruby-2.0.0.p598-1.mbs2.x86_64.rpm 1fcae47502636f81267d2091d2e6f16a mbs2/x86_64/ruby-devel-2.0.0.p598-1.mbs2.x86_64.rpm 11d103d52f5050ee72abb7313f6c92f0 mbs2/x86_64/ruby-doc-2.0.0.p598-1.mbs2.noarch.rpm bab70f79054bac5869ac9d94301e761a mbs2/x86_64/ruby-irb-2.0.0.p598-1.mbs2.noarch.rpm aef9f2690106b692cfbb0c9808722033 mbs2/x86_64/ruby-tk-2.0.0.p598-1.mbs2.x86_64.rpm 3a6998dd32576a04a1af77d0698bcc28 mbs2/SRPMS/ruby-2.0.0.p598-1.mbs2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
