Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2005-3416 medium priority: Ubuntu including 1 source packages (phpbb2), 4 status rows across 4 suites (dapper, edgy, feisty, upstream): released 3, needs-triage 1.
phpBB 2.0.17 and earlier, when register_globals is enabled and the session_start function has not been called to handle a session, allows remote attackers to bypass security checks by setting the $_SESSION and $HTTP_SESSION_VARS variables to strings instead of arrays, which causes an array_merge function call to fail.
