"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).

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
