Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2011-0073 medium priority: Ubuntu including 6 source packages (firefox, firefox-3.0, firefox-3.5, seamonkey, thunderbird, xulrunner-1.9.2), 68 status rows across 12 suites (dapper, hardy, karmic, lucid, maverick, natty, oneiric, precise, quantal, raring, saucy, upstream): DNE 31, released 16, not-affected 11, ignored 8, needs-triage 2.
Mozilla Firefox before 3.5.19 and 3.6.x before 3.6.17, and SeaMonkey before 2.0.14, does not properly use nsTreeRange data structures, which allows remote attackers to execute arbitrary code via unspecified vectors that lead to a "dangling pointer."
