Summary
ruby1.8, ruby1.9.1, ruby2.0, ruby2.1 vulnerabilities
Details
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)
Willis Vandevanter discovered that Ruby incorrectly handled XML entity expansion. An attacker could use this flaw to cause Ruby to consume large amounts of resources, resulting in a denial of service. (CVE-2014-8080)
