Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2016-3705 low priority: Ubuntu including 1 source packages (libxml2), 7 status rows across 7 suites (precise, trusty, upstream, wily, xenial, yakkety, zesty): released 5, not-affected 2.
The (1) xmlParserEntityCheck and (2) xmlParseAttValueComplex functions in parser.c in libxml2 2.9.3 do not properly keep track of the recursion depth, which allows context-dependent attackers to cause a denial of service (stack consumption and application crash) via a crafted XML document containing a large number of nested entity references.
