 Mandriva Linux Security Advisory                         MDVSA-2013:124

 Package : ruby
 Date    : April 10, 2013
 Affected: Business Server 1.0
 _______________________________________________________________________

 Problem Description:

 Updated ruby packages fix security vulnerabilities:
 
 Shugo Maedo and Vit Ondruch discovered that Ruby incorrectly allowed
 untainted strings to be modified in protective safe levels. An
 attacker could use this flaw to bypass intended access restrictions
 (CVE-2012-4466, CVE-2012-4481).
 
 It was discovered that Ruby's REXML library did not properly restrict
 XML entity expansion. An attacker could use this flaw to cause a
 denial of service by tricking a Ruby application using REXML to read
 text nodes from specially-crafted XML content, which will result in
 REXML consuming large amounts of system memory (CVE-2013-1821).
