Multiple vulnerabilities were discovered in the interpreter for the Ruby language :
CVE-2014-4975 The encodes() function in pack.c had an off-by-one error that could lead to a stack-based buffer overflow. This could allow remote attackers to cause a denial of service (crash) or arbitrary code execution.
CVE-2014-8080, CVE-2014-8090 The REXML parser could be coerced into allocating large string objects that could consume all available memory on the system. This could allow remote attackers to cause a denial of service (crash).
