Details

Jean-Philippe Aumasson discovered that Ruby incorrectly generated
predictable hash values. An attacker could use this issue to generate hash
collisions and cause a denial of service. (CVE-2012-5371)

Evgeny Ermakov discovered that documentation generated by rdoc is
vulnerable to a cross-site scripting issue. With cross-site scripting
vulnerabilities, if a user were tricked into viewing a specially crafted
page, a remote attacker could exploit this to modify the contents, or steal
confidential data, within the same domain. (CVE-2013-0256)

Thomas Hollstegge and Ben Murphy discovered that the JSON implementation
in Ruby incorrectly handled certain crafted documents. An attacker could
use this issue to cause a denial of service or bypass certain protection
mechanisms. (CVE-2013-0269)
