Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2011-1947 unimportant priority: Debian including 1 source packages (fetchmail), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
fetchmail 5.9.9 through 6.3.19 does not properly limit the wait time after issuing a (1) STARTTLS or (2) STLS request, which allows remote servers to cause a denial of service (application hang) by acknowledging the request but not sending additional packets.
