Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2015-8317 low priority: Ubuntu including 1 source packages (libxml2), 5 status rows across 5 suites (precise, trusty, upstream, vivid, wily): released 4, not-affected 1.
The xmlParseXMLDecl function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to obtain sensitive information via an (1) unterminated encoding value or (2) incomplete XML declaration in XML data, which triggers an out-of-bounds heap read.
