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).");
