Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2014-2576 low priority: Ubuntu including 1 source packages (claws-mail-extra-plugins), 12 status rows across 12 suites (lucid, precise, quantal, saucy, trusty, upstream, utopic, vivid, wily, xenial, yakkety, zesty): DNE 7, ignored 4, needs-triage 1.
plugins/rssyl/feed.c in Claws Mail before 3.10.0 disables the CURLOPT_SSL_VERIFYHOST check for CN or SAN host name fields, which makes it easier for remote attackers to spoof servers and conduct man-in-the-middle (MITM) attacks.
