Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2011-1499 medium priority: Ubuntu including 1 source packages (tinyproxy), 11 status rows across 11 suites (dapper, hardy, lucid, maverick, natty, oneiric, precise, quantal, raring, saucy, upstream): not-affected 5, ignored 3, released 3.
acl.c in Tinyproxy before 1.8.3, when an Allow configuration setting specifies a CIDR block, permits TCP connections from all IP addresses, which makes it easier for remote attackers to hide the origin of web traffic by leveraging the open HTTP proxy server.
