Mandriva Linux Security Advisory 2015-129 - 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. 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. Due to an incomplete fix for 100% CPU utilization can occur as a result of recursive expansion with an empty String.

Red Hat Security Advisory 2014-1914-01 - Ruby is an extensible, interpreted, object-oriented, scripting language. It has features to process text files and to perform system management tasks. Multiple denial of service flaws were found in the way the Ruby REXML XML parser performed expansion of parameter entities. A specially crafted XML document could cause REXML to use an excessive amount of CPU and memory. A stack-based buffer overflow was found in the implementation of the Ruby Array pack() method. When performing base64 encoding, a single byte could be written past the end of the buffer, possibly causing Ruby to crash.

Ubuntu Security Notice 2397-1 - 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. 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. Various other issues were also addressed.
