Red Hat Product Security has rated this update as having Moderate
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

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. (CVE-2014-8080, CVE-2014-8090)

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. (CVE-2014-4975)

The CVE-2014-8090 issue was discovered by Red Hat Product Security.

All ruby users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. All running
instances of Ruby need to be restarted for this update to take effect."

    before 2.0.0-p594, and 2.1.x before 2.1.4 allows remote
    attackers to cause a denial of service (memory
    consumption) via a crafted XML document, aka an XML
    Entity Expansion (XEE) attack.i1/4^CVE-2014-8080i1/4%0

  - The REXML parser in Ruby 1.9.x before 1.9.3 patchlevel
    551, 2.0.x before 2.0.0 patchlevel 598, and 2.1.x
    before 2.1.5 allows remote attackers to cause a denial
    of service (CPU and memory consumption) a crafted XML
    document containing an empty string in an entity that
    is used in a large number of nested entity references,
    aka an XML Entity Expansion (XEE) attack. NOTE: this
    vulnerability exists because of an incomplete fix for
    CVE-2013-1821 and CVE-2014-8080.i1/4^CVE-2014-8090i1/4%0

  - Off-by-one error in the encodes function in pack.c in
    Ruby 1.9.3 and earlier, and 2.x through 2.1.2, when
    using certain format string specifiers, allows
    context-dependent attackers to cause a denial of
    service (segmentation fault) via vectors that trigger a
    stack-based buffer overflow.(CVE-2014-4975)
