Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2017-18196 low priority: Ubuntu including 1 source packages (leptonlib), 13 status rows across 13 suites (artful, bionic, cosmic, disco, eoan, focal, groovy, hirsute, impish, jammy, trusty, upstream, xenial): not-affected 10, released 2, ignored 1.
Leptonica 1.74.4 constructs unintended pathnames (containing duplicated path components) when operating on files in /tmp subdirectories, which might allow local users to bypass intended file restrictions by leveraging access to a directory located deeper within the /tmp directory tree, as demonstrated by /tmp/ANY/PATH/ANY/PATH/input.tif.
