"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)."
