CVE-2014-4975 [MEDIUM] Ruby vulnerabilities
Title: Ruby vulnerabilities
Summary: Several security issues were fixed in Ruby.
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)
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2014-8090 ruby: REXML incomplete fix for CVE-2014-8080
The CVE-2014-8080 (tracked via bug 1157709) was assigned to a "billion laughs" issue affecting the Ruby REXML XML parser. The issue affected expansion of parameter entities, making it possible for a small XML document to cause the parser to use excessive amount of CPU and memory while parsing.
The upstream patch for CVE-2014-8080 introduced checks against the REXML.entity_expansion_text_limit, but did not add restrictions to limit the number of expansions performed, i.e. checks against the REXML::Document.entity_expansion_limit. As a consequence, even with the patch applied, a small XML document could cause REXML to use an excessive amount of CPU time. High memory usage can be achieved using larger inputs.
