Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2018-7186 medium 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 9, released 2, ignored 1, needs-triage 1.
Leptonica before 1.75.3 does not limit the number of characters in a %s format argument to fscanf or sscanf, which allows remote attackers to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a long string, as demonstrated by the gplotRead and ptaReadStream functions.
